We're experimenting and would love to hear from you!In this episode of Discover Daily, we explore OpenAI's announcement of their latest AI model, o3. This revolutionary model features enhanced reasoning capabilities, improved coding abilities, and innovative chain-of-thought processing. OpenAI's cautious approach includes initial restricted access to safety researchers, with a phased release strategy planning to introduce o3-mini by January 2025.The FDA's comprehensive update to its 'healthy' nutrient content claim marks a significant shift in food labeling standards. The new criteria emphasize nutrient-dense foods while limiting added sugars, allowing previously excluded foods like salmon and avocados to qualify for the 'healthy' label. These changes are projected to save $686 million in chronic disease-related costs over 20 years, though manufacturers face substantial reformulation expenses.The spotlight story features Genesis, dubbed the world's fastest physics engine, developed through collaboration among 20+ research labs. This platform can run simulations up to 430,000 times faster than real-time on an RTX 4090 GPU, with practical applications ranging from robotics to video game development. As an open-source Python platform, Genesis promises to revolutionize physics simulations across multiple industries, from materials science to aerospace engineering.From Perplexity's Discover Feed:https://www.perplexity.ai/page/openai-debuts-o3-model-GxpSIB3_SiGhYuMk_KtczAhttps://www.perplexity.ai/page/fda-s-new-healthy-food-label-_K__20YMRU65jGsxFzHOcAhttps://www.perplexity.ai/page/genesis-world-s-fastest-physic-2_AOTm8gQZ2edfo0ywBX4APerplexity is the fastest and most powerful way to search the web.

Today's guest is Diego Oliveira Sanchez, founder of NutriAdmin — a nutrition software designed to help nutritionists, health coaches, and personal trainers manage their clients and work more efficiently. Diego discusses how his personal health journey led him to create the software, NutriAdmin's features for consultations, meal planning, client portals, follow-up care, etc., and how the software makes it easy for health coaches to customize nutrition for their clients.   In this episode, we talk about: What is NutriAdmin and how it helps health coaches How poor diet and weight gain in university led Diego to launch NutriAdmin Some common pain points nutritionists and health coaches face Key aspects of the NutriAdmin user experience — the meal plan generator, note-taking during consultations, client portals, etc. NutriAdmin's suitability for other professionals like nurses or mental health specialists How long does it take users to learn how to use NutriAdmin Examples of success clients have seen with NutriAdmin The free trial, money-back guarantee, and resources available on NutriAdmin   Memorable Quotes   “I want to help in any way I can, for more people to have access to nutrition, to great education so that they can improve their health.”   “A lot of people work in the fitness industry, and they are kind of mastering the fitness part. They're coaching their clients, they are doing the exercise, but then the clients are not eating well. And it's probably impossible, or really hard, to get fit if you're exercising but you're not eating well.”   BIO:  Diego is the co-founder of NutriAdmin (nutriadmin.com) - a leading software for nutritionists and coaches launched in 2016. For Diego, NutriAdmin combines his two passions: software and nutrition. Diego has a background in Scientific Computing from Cambridge University and has been writing code since 2009. Diego has also been passionate about nutrition for more than a decade. It's personal. Whilst at uni, Diego gained 35Kg through an unhealthy diet, reaching a dangerous weight. Then, after reading dozens of books in nutrition and with the invaluable help of a nutrition coach, Diego has lost all excess weight, regained his health, and stayed at high fitness levels for over a decade. Diego has seen (on himself and countless others) how nutrition and coaching have tremendous power to transform people's health. The dream with NutriAdmin is to help nutritionists and coaches to reach more clients, so that they regain their health and become their best selves.

This episode's conversation between host Peter Wang and Ryan Abernathey, Associate Professor at Columbia University in the City of New York, explores climate science, scientific computing, data accessibility, and more.    Topics that Peter and Ryan cover include: - Cloud computing - Open data and collaboration - Climate science and the private sector - Open-source projects like Pangeo Forge and Xarray   Climate data is sometimes restricted in the way it flows between interested parties; the growth of private industry around data storage and dissemination has put up barriers to entry that can limit access to valuable systems and data. This is especially troubling to Ryan because these barriers often exclude some of the people who are most affected by climate change. He feels that usable information can and should be made accessible without undermining private interests.   Peter Wang - https://www.linkedin.com/in/pzwang/ Ryan Abernathey - https://www.linkedin.com/in/ryan-abernathey-32a70652/ Columbia University in the City of New York - https://www.linkedin.com/school/columbia-university/ Pangeo Forge - https://pangeo-forge.org/ Xarray - https://docs.xarray.dev/en/stable/   You can find a human-verified transcript of this episode here. - https://know.anaconda.com/rs/387-XNW-688/images/ANACON_%20Ryan%20Abernathey_HVT.docx.pdf   If you enjoyed today's show, please leave a 5-star review.

Nick Hinton is known as a conspiracy theory gurus on Twitter; he first got major attention for his Saturn Time Cube posts-----Intro - 00:15Ads - 07:44 - Please visit our sponsors Awakened Vapes, Genesis Pharms, and the Caramel Corn Company and help support this podcast!Interview - 11:19-----Welcome back to Awakened Exchanges! I'm your host Jay Rich and this is our first holiday episode! This whole month I'll be focused on fun things that bring me, and hopefully you, joy. Our first episode this month is with Nick Hinton himself, and if the name sounds familiar, that's probably because you know him as “the conspiracy guy on Twitter.” If everything goes as planned, we should have a very special Christmas Eve with a former member of the Borg themselves! Stay tuned for more info!My introduction to Nick was because of a Mandela Effect post that happened to catch my eye. I've been interested in the subject since my introduction to the Berenstain vs Berenstein Bears phenomenon. Once I started researching, I found that there were a few things that stuck with me on the anomalous side, whereas a few I remembered “the correct way.” While I'm sure that memory is malleable, I also started seriously considering what bigger implications could be made. I'm a believer in Hugh Everett's Multiverse Hypothesis, but I like to think of the decision tree as branchial time,  where each decision can branch off into multiple lines. If most of those decisions only affect you or a limited number of people, then you can think of those branches eventually being clipped back off into what we'll call the current consensus reality. My particular thought is, what if the Mandela Effect was actually caused by larger branches of time that were merged on top of one another? Two similar universes, with minor differences in the timeline, dimensionally merged together somehow. This is where I bring up CERN and the fact that the Large Hadron Collider was built in 2008...the year before Fiona Broome launched the Mandela Effect website to ask people if they also remembered Nelson Mandela's funeral, even though he didn't die until 2013. There was talk early on about the collider possibly causing miniature black holes, but scientists weren't concerned as they would burn themselves out before reaching critical mass. That said, in November 2009, Sergio Bertolucci, the Director for Research and Scientific Computing at CERN, said that what they were attempting to do was akin to opening a door and that, I quote, "Out of this door might come something, or we might send something through it." That may have you thinking about Stranger Things and The Upside Down, but what if that door was just to one, or many, very similar realities that share space with us here and now? More in the podcast.I get the feeling that there are a large number of our audience this week that will be coming here to hear Nick speak.  Nick is known as one of the conspiracy theory gurus on Twitter and he first got major attention for his Saturn Time Cube posts. He had compiled a lot of information from various sources and made it a lot more accessible for psychonauts and conspiracy buffs to make it through, eventually publishing his first book on the subject.  I get the feeling that we could have gotten going on a number of topics and I hope to have him back on the show someday to do just that. This was one of my favorite conversations yet, and I truly hope that you enjoy this fun little holiday gift to kick off December. Support the show (https://www.patreon.com/AwakenedExchanges) --- Send in a voice message: https://podcasters.spotify.com/pod/show/awakened-exchanges/message Support this podcast: https://podcasters.spotify.com/pod/show/awakened-exchanges/support

On this episode, we'll speak with one of the principal researchers on the Wolfram Physics Project, Jonathan Gorard. We'll discuss how they plan to actually implement their “fundamental theory of the universe” and build these computational universes. Jonathan Gorard is a theoretical mathematician, researcher at the University of Cambridge, and consultant to Wolfram Research. He is ostensibly the scientist tasked with doing the maths to demonstrate these concepts to the scientific community and the public. Actually proving these ideas out in the open, over the din of more than a few detractors, may be one of the most difficult parts of this highly complex project. Along with a call for scientists everywhere to contribute and critique the project in an open-source manner, the team published nearly a thousand pages and over 500 hours of video. All since Wolfram's announcement on April 14th titled, “We may have found a fundamental theory of the universe… and it's beautiful.” The Wolfram Physics team, consisting of Stephen Wolfram, Jonathan Gorard, and theoretical physicist and competitive programmer Max Piskanov, are literally live-streaming the entire thing. Scientific discovery, open collaboration, and peer review happening in real-time, and anyone can get involved. Now that is beautiful. This is the TomorrowScale podcast, hosted by Justin Briggs.

In episode 27, we interviewed Ralf Gommers from the NumPy and SciPy projects. We started our discussion by talking about his past research experience as a physicist and his transition to open source software and programming. This led him to get involved in projects such as PyWavelets, NumPy and SciPy. Following that, we had a great discussion about NumPy, its many features, its target audience and its performance. We learned why NumPy is not included in Python's standard library and its overlap with Scipy. We also compared the combination of Matlab to NumPy and Python and how users could transition to this open source solution. We then had a brief discussion about SciPy and the features it provides. Ralf informed us of the positive results from Google's previous Summer of Code and Season of Docs participations. We discussed how to reach the project and the many kinds of contributions that they are looking for. We talked about the importance of FLOSS for science and attribution of research output. We finished the interview with our classic quick questions and a reflection from Ralf about the need for more sustainability in open source software development as volunteer effort may not be sufficient in the future. 00:00:00 Intro 00:00:18 Introduction 00:00:33 Introducing Ralf Gommers 00:02:05 Research during his PhD and and PostDoc 00:03:20 When he started to use open source tools 00:03:52 Learning to code 00:04:39 PyWavelets, another sideproject he likes 00:05:55 His elevator pitch for NumPy 00:06:55 Vector arrays in Python before NumPy 00:07:49 How he got involved in the NumPy project 00:10:13 Traget users for NumPy 00:11:36 NumPy as part of the standard library? 00:13:24 Features provided by NumPy 00:14:22 Major differences between Python built-in list and NumPy's array 00:16:01 Structured data 00:16:45 Why appending a row to an array is made hard 00:18:09 Multithreaded code with NumPy 00:19:48 Distributed array processing 00:20:50 GPU computation with Python and NumPy 00:22:16 Linear algebra functions in NumPy 00:23:25 Overlap between SciPy and NumPy for linear algebra 00:23:55 Python speed as an interpreted language 00:25:43 Python with NumPy compared to Matlab 00:28:07 How easy is the transition between Matlab and Python Numpy 00:29:26 Performance difference between Matlab and Python 00:31:00 Commercial applications of NumPy 00:32:15 Contributions from the industry ans incentives to contribute 00:34:10 Elevator pitch for SciPy 00:35:37 Overview of some of the submodules in SciPy 00:38:11 The size of the communities 00:39:33 Participation in Google Summer of Code 00:40:24 Participation in Google Season of Docs 00:41:48 Communication channels in the project 00:43:25 Where to ask for support? 00:44:48 Possible contributions 00:46:25 Skills usefull to contribute to the NumPy project 00:48:12 Identifying possible contributions 00:48:52 The importance of FLOSS for science 00:52:02 Possible negative impact of FLOSS on science 00:52:49 Crediting contributions in science 00:53:42 Most notable scientific discovery in recent years 00:54:49 His favourite text processing tool 00:55:30 Volunteer effort may not be sufficient anymore 00:56:58 Contact informations for Ralf Gommers 00:57:27 Outro

This week on our debut episode I discuss Hyperspace with Dr Gaurav Khanna www.linkedin.com/in/gaurav-khanna a Professor in the Physics Department, and the Associate Director of the Center for Scientific Computing at the University of Massachusetts Dartmouth. He works on a variety of challenging problems in theoretical and computational physics. Dr Gaurav introduces me to hyperspace and blackholes and as a non-scientist (although learning everyday) I learn very quickly that in theory travel through a blackhole won't necessarily be dangerous at all. In fact science indicates the 'Yes' if you have a large enough blackhole and if it is spinning fast enough then travel through would be safe and that the main issue is what is on the other side of the singularity?

In episode 21, we interviewed Juan Pablo Carbajal, an Argentinian physicist currently working as a postdoctoral researcher in the Department of Urban Water Management at the ETH domain in Switzerland. We had a great discussion about GNU Octave and how it can help scientists. We compared its core functions and its expandability through packages to its commercial equivalent Matlab and its toolboxes. An interesting feature of GNU Octave that we explored with Juan is the possibility to migrate code from Matlab directly to GNU Octave and to a certain point maintain code compatible with both. Juan shared with us that since the introduction of an integrated GUI in 2015, he noticed a continuous growth in popularity for the project. We then discussed about a few of the reasons why companies are interested by GNU Octave and why universities should teach using free/libre software. Before asking our usual quick questions, Juan talked with us about the reasons why FLOSS is important for science and the importance of exposing non-FLOSS users to the benefits of FLOSS. 00:00:00 Message to our listeners 00:00:29 Intro 00:00:45 Introducing Juan Pablo Carbajal 00:01:32 30 seconds elevator pitch for GNU Octave 00:02:20 How does the Octave programming language compares to other common programming languages 00:03:23 Compatibility between GNU Octave and Matlab 00:06:29 Matlab's toolboxes compared to GNU Octave packages 00:07:31 Simulink models with GNU Octave 00:09:06 Parallel processing with GNU Octave 00:10:40 The issue with CUDA in GNU Octave 00:11:48 How GNU Octaves differs rom other open source Matlab equivalents 00:13:34 Syntax compatibility to ease transition and reusing code from Matlab 00:15:11 Resources to start using GNU Octave 00:16:40 GNU Octave's graphical user interface and the old QT Octave GUI 00:20:14 GNU Octave's graphical user interface compared to Matlab 00:22:11 Why GNU Octave and not simply Octave 00:23:06 GNU Octave licence 00:24:01 How often he uses GNU Octave 00:24:18 Juan's numerous contributions to the project 00:25:27 GNU octave for companies 00:27:45 Arguments for teaching with GNU Octave instead of Matlab 00:29:32 How many are involved in the project? 00:30:37 Communication channels within the project 00:31:34 Is the project actively looking for developers? 00:32:11 Skills required to contribute 00:33:14 The two-level language dilemma 00:34:59 Juan's vision about FLOSS and its importance for science 00:37:09 Possible negative impacts of FLOSS and converting non-FLOSS users 00:40:17 The most notable scientific discovery in recent years 00:41:46 Juan's favourite text processing tools 00:42:38 Things we forgot to ask about 00:43:57 Anything else to share? 00:44:25 How to contact Juan 00:44:50 Outro

Researcher Dr. Eva Lee joins Tim to discuss her work on the front lines in the battle against the opioid epidemic. Dr. Lee is a professor in the School of Industrial and Systems Engineering at Georgia Tech, and Director of the Center for Operations Research in Medicine and HealthCare, and her not-so-secret weapons are math, data and analytics. https://traffic.libsyn.com/shapingopinion/Opioids_-_Start_by_protecting_the_innocents_-_Episode_27.mp3   In this episode, we talk with Dr. Lee about her work in trying to tackle challenging problems associated with the nation’s opioid epidemic and how perceptions in the medical community is one key area of focus. This bonus episode is a break from our normal pattern at the Shaping Opinion podcast. Usually, we talk about people, events or things that have found a place in history that truly have shaped the way we think. The nation’s opioid epidemic is different, however. The opioid epidemic is happening now. It’s not history. Our perceptions of the seeming harmlessness of a painkiller or a cough medicine may lead us to choose comfort over temporary discomfort, which has the potential to lead to complications from taking opioids. When we talked to Dr. Eva Lee, we learned that math can be used to identify patient care practices with the best outcomes, and that if those practices spread, society can start to take significant measures to counter the opioid epidemic. Dr. Lee focused her research on the youngest and most vulnerable among us, babies. But not healthy babies. These are babies born with heart defects that typically begin their lives in the Intensive Care Unit and face serious surgeries in the first year of their lives. They are prescribed opioids to alleviate their suffering. But where do we get to the point where the opioids can cause more problems than they solve? And most importantly, what can we learn from Dr. Lee’s research in this area to expand those lessons to children and adults so that the nation can form a more broad-based attack on the opioid epidemic? Dr. Lee is a professor in the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech, and she is Director of the Center for Operations Research in Medicine and HealthCare. She is also a Senior Research Professor at the Atlanta VA Medical Center. She uses mathematical programming and large-scale computational algorithms to help medical and healthcare decision-making. She tackles challenging problems in health systems and biomedicine by bringing a math perspective to healthcare, through systems modeling, algorithm and software design, and decision theory analysis. This work creates a better understanding of what works based on data and analytics so that patient care guidelines across the country can be improved. Dr. Lee was part of a team that was a finalist for a prestigious honor for this work. It is the Franz Edelman Award from the Institute for Operations Research and the Management Sciences (INFORMS). We talked to Dr. Eva Lee about her research and what it means from actual health care practices, to doctor and patient perceptions.

Das Treffens des German Chapters of European Women in Mathematics fand am 3. und 4. Mai 2018 im Mathematikon in Heidelberg statt. Am Rande der Konferenz der Mathematikerinnen sprach Gudrun mit Susanne Krömker. Sie leitet seit 2004 die Computergrafik-Gruppe des Interdisziplinären Zentrums für Wissenschaftliches Rechnen(IWR) an der Ruprecht-Karls-Universität Heidelberg. In der Computergrafik geht es grob gesagt um Analyse und Bearbeitung von Daten und ihre Darstellung als visuelle Information, d.h. es kommen sehr viele unterschiedliche Anforderungen zusammen. Andererseits sind die Themen, die jeweils dahinter stecken auch ganz besonders vielgestaltig. Für Susanne begann 1989 die Faszination mit der Darstellung einer reaktiven Strömung, bei der explosionsartig Wärme freigesetzt wird. Im Experiment ist die Apparatur geborsten, die Simulation liefert die Erklärung durch eine von den Wänden reflektierte Druckwelle und die Visualisierung macht den zeitlich enorm kurzen Explosionsvorgang mit Temperatur- und Druckverteilung im reaktiven Gemisch anschaulich. Anschließend hat sie sich in ihrer Promotion mit partiellen Differentialgleichungen zur Beschreibung katalytischer Prozesse an Oberflächen beschäftigt, sich aber nie ganz von dem Thema Computergrafik getrennt, das in den 1990er Jahren dann richtig Fahrt aufnahm. Heute ist die Computergrafik technisch gesehen eine typische Anwendung für Hochleistungsrechnen. Außerdem gibt es immer wieder interessante Entwicklungen, die die Möglichkeiten von Grafikkarten unkonventionell ausnutzen. Aber es geht auch darum, geeignete Methoden zu entwicklen und zu implementieren, mit denen die von 3D-Scannern erfassten Messdaten auf ihren Informationsgehalt reduziert werden können. Grundsätzlich müssen dabei immer dreidimensionale Vorgänge auf dem zweidimensionalen Bildschirm dargestellt werden. Dazu braucht man projektive Geometrie - ein Thema, das in der Vorlesung mitunter abstrakt und von der Realität weit entfernt scheint. In ihrer Geometrie-Vorlesung für Sudierende der Mathematik kann Susanne ihre Erfahrungen aus der Informatik sehr anschaulich einbringen wie hier im Video für die Fano Ebene: (YouTube) Etwa seit dem Jahr 2000 gab es in der Arbeitsgruppe von Susanne viele besonders interessante und sehr unterschiedliche Projekte. Ein Forschungsschwerpunkt lag dabei in der Kombination von Computertomographie und Oberflächendaten, um aus beiden Bildgebungsverfahren im Resultat ein verbessertes Bild zu erhalten: ILATO-Projekt (Improving Limited Angle computed Tomography by Optical data integration). Außerdem hat sich die enge Zusammenarbeit mit Archäologen, Historikern und Geologen als besonders fruchtbar erwiesen. Beispiele dafür sind der theoriebildende Diskurs zum digitalen Modell des Klosters Lorsch (seit 1991 Weltkulturerbe der UNESCO) oder die Rekonstruktion von Inschriften in Tafeln und auf Grabsteinen, z.B. auf dem jüdischen Friedhof in Worms. Diese Analyse basiert auf Multiskalen Integralinvarianten, einem Filterverfahren, das in dem Softwareframework GigaMesh (Autor: Hubert Mara, IWR, Universität Heidelberg) implementiert ist. Oder die Rekonstruktion der Karten von barocken Globen, u.a. des Gottorfer Globus, mit HiIfe von anisotrop diffusiver Filterung. Die Arbeitsgruppe hat Ausgrabungen im Tempelgebiet von Angkor in Kambodscha, dem größten Tempelgebiet der Welt, wissenschaftlich begleitet. Es gelang eine virtuelle architektonische Rekonstruktion des größten Tempels Angkor Wat oder die Rekonstruktion einer sechs Meter hohen Schiva-Statue aus Koh Ker, von der einzelne Puzzle-Teile über mehrere Museen der Welt verstreut sind. Susanne hatte sich 1983 zunächst für ein Studium der Mathematik und Betriebswirtschaft in Osnabrück entschieden, hat dann aber den Wechsel nach Heidelberg verbunden mit der Hinwendungen zu anderen Natur- und Geisteswissenschaften nie bereut.

Gudrun hatte zwei Podcast-Gespräche beim FEniCS18 Workshop in Oxford (21.-23. März 2018). FEniCS ist eine Open-Source-Plattform zur Lösung partieller Differentialgleichungen mit Finite-Elemente-Methoden. Dies ist die zweite der beiden 2018er Folgen aus Oxford. Susanne Claus ist zur Zeit NRN Early Career Personal Research Fellow an der Cardiff University in Wales. Sie hat sich schon immer für Mathematik, Physik, Informatik und Ingenieursthemen interesseirt und diese Interessen in einem Studium der Technomathematik in Kaiserlautern verbunden. Mit dem Vordiplom in der Tasche entschied sie sich für einen einjährigen Aufenthalt an der Universität Kyoto. Sie war dort ein Research exchange student und hat neben der Teilnahme an Vorlesungen vor allem eine Forschungsarbeit zu Verdunstungsprozessen geschrieben. Damit waren die Weichen in Richtung Strömungsrechnung gestellt. Dieses Interesse vertiefte sie im Hauptstudium (bis zum Diplom) an der Uni in Bonn, wo sie auch als studentische Hilfskraft in der Numerik mitarbeitete. Die dabei erwachte Begeisterung für nicht-Newtonsche Fluid-Modelle führte sie schließlich für die Promotion nach Cardiff. Dort werden schon in langer Tradition sogenannte viskoelastische Stoffe untersucht - das ist eine spezielle Klasse von nicht-Newtonschem Fluiden. Nach der Promotion arbeitet sie einige Zeit als Postdoc in London am University College London (kurz: UCL) zu Fehleranalyse für Finite Elemente Verfahren (*). Bis sie mit einer selbst eingeworbenen Fellowship in der Tasche wieder nach Cardiff zurückkehren konnte. Im Moment beschäftigt sich Susanne vor allem mit Zweiphasenströmungen. In realen Strömungsprozessen liegen eigentlich immer mindestens zwei Phasen vor: z.B. Luft und Wasser. Das ist der Fall wenn wir den Wasserhahn aufdrehen oder die Strömung eines Flusses beobachten. Sehr häufig werden solche Prozesse vereinfacht modelliert, indem man sich nur eine Phase, nämlich die des Wassers genau ansieht und die andere als nicht so wichtig weglässt. In der Modellbildung für Probleme, in denen beide Phasen betrachtet werden sollen, ist das erste Problem, dass das physikalische Verhalten der beiden Phasen sehr unterschiedlich ist, d.h. man braucht in der Regel zwei sehr unterschiedliche Modelle. Hinzu treten dann noch komplexe Vorgänge auf der Grenzflächen auf z.B. in der Wechselwirkung der Phasen. Wo die Grenzfläche zu jedem Zeitpunkt verläuft, ist selbst Teil der Lösung des Problems. Noch interessanter aber auch besonders schwierig wird es, wenn auf der Grenzfläche Tenside wirken (engl. surfactant) - das sind Chemikalien die auch die Geometrie der Grenzfläche verändern, weil sie Einfluß auf die Oberflächenspannung nehmen. Ein Zwischenschritt ist es, wenn man nur eine Phase betrachtet, aber im Fließprozess eine freie Oberfläche erlaubt. Die Entwicklung dieser Oberfläche über die Zeit wird oft über die Minimierung von Oberflächenspannung modelliert und hängt deshalb u.a. mit der Krümmung der Fläche zusammen. D.h. man braucht im Modell lokale Informationen über zweite Ableitungen. In der numerischen Bearbeitung des Prozesses benutzt Susanne das FEniCS Framework. Das hat sie auch konkret dieses Jahr nach Oxford zum Workshop geführt. Ihr Ansatz ist es, das Rechengitter um genug Knoten anzureichern, so dass Sprünge dargestellt werden können ohne eine zu hohe Auflösung insgesamt zu verursachen. (*) an der UCL arbeitet auch Helen Wilson zu viscoelastischen Strömungen, mit der Gudrun 2016 in Oxford gesprochen hat. Literatur und weiterführende Informationen S. Claus & P.
