Following on from my earlier stuff about being inspired about parachute/recovery systems and Ballute design in @FreeCAD I've dived into setting up the CfDoF workbench and bashing through a simple tutorial pushing water through a stepped tube. I think I borked the glyph a little, but I feel like I've learnt a little... and seen a LOT to learn. #OpenFOAM #CFD #Paraview

Great evening speaking at and helping run a North Wales Tech meetup event locally this evening. Great to see some of the @DoESLiverpool crew come over! @goatchurch gave an excellent presentation on @FreeCAD #paraview and using the #godot engine to build multiplayer #vr viewing environments for engineers.

Julian speaking about using paraview and VR to create immersive visualisations of CFD.

Next up at #FreeCADDay is Julian @goatchurch speaking about #Godot as a front end for #VR / #XR interaction with #Paraview.

Die freien Tage hatte ich für meinen richtigen Trainingsauftakt genutzt, und ich hatte endlich mal wieder Zeit für das #Velomobil. Mit #FreeCAD ist es Möglich den Rechner in einen #Windkanal zu verwandeln. Die Workbench #CfdOF nutzt den Ventilator des Prozessors, um mächtig Wind zu erzeugen. Mit #ParaView können die mit Hilfe von #OpenFOAM erzeugten Ergebnisse ausgewertet werden.

Registration for the upcoming (free) virtual ANARI Hackathon on Oct. 21-23 is now open!

Come join us to work on various projects related to ANARI -- we will be meeting via Zoom to "divide and conquer" on all kinds of fun things to work on.

🎉 I‘m happy to announce that I was invited as keynote speaker for this year‘s ParaView User Day Europe! 🇪🇺

In the last couple of years at #NHR4CES we have been working towards bringing visualization to the HPC community, while also enabling visualization scientists to make use of HPC infrastructure. 🤝

In this journey, #ParaView has played an essential part (with all its up- and downsides 😅).

I’m excited to talk about that journey this September in Lyon 🇫🇷 and connect with users and researchers

I've been working on thermal support in #GPUSPH, and was finally at the stage where I could run some tests and check the results. Except that #ParaView was refusing to open my files, complaining about “invalid token”s. I just spent over half an hour trying to understand what I changed in my code that had broken the output, even though I haven't changed anything related to it recently … turns out it wasn't my problem, but an issue with an upgrade ParaView and libexpat:

Exploring the Venturi effect.

A simulation was performed to create this model which depicts streamlines within a tube. The lines are coloured to show that the pressure at the throat section is lower (blue) than the pressure at the inlet or outlet sections (red).

@Zamfr @ahafeezs Doing it the more hassle way, but it kind a works fine. Not the biggest of #paraview (fine software and well build), but I prefer a clear 2d graph everyday over an 3d image 🙃

Mastodon #introduction: TuxRiders is a journey to research experiences using free and #opensource scientific computing programs, which aimed to demonstrate their power for real-world scientific research.

In our #YouTube channel, we regularly talk about #FiniteElement, #EngineeringMath, #PDEs, #NumericalMethods, #FreeFEM, #FEniCS, #ParaView, #C++, #Python, #OpenFOAM, and #Linux.

PyVista is powerful, extremely intuitive, and almost completely replaces my usage of #ParaView. It is my first choice for almost any #3D #Dataviz in #Python now 🫀

Before doing any #ML in #MedicalImaging, getting familiar with the data helps.

Here is how to visualize the whole training set for the 3D Left Atrial Segmentation Challenge (https://kaggle.com/datasets/adarshsng/heart-mri-image-dataset-left-atrial-segmentation) by Cata Tobon-Gomez and Arjan Geers:

All in a few lines of code, with IO, image slicing, meshing, or widgets.

#FreeCAD's HarryvL has added the (WIP) #FEM/#FEA critical plastic strain ratio as a post-processing step for #CalculiX results. This is available from the #VTK pipeline + for export to #ParaView.

#Paraview is #opensourcesoftware! It's integrated into many other projects and can be used with FreeCAD and LadyBug Tools as well as many other.

Supporting companies like Kitware Europe supports their contributions to open source technologies.

#openEMS and #paraview?
yes, although the first must be built from source, and the second has disappeared from #DragonFlyBSD ports for some reason, maybe there are still in Linux packages:)
