Having Just Realized™ that I can use Sphere Glyphs to render my particles in #ParaView, I am now Very Happy™ because my low-resolution #SPH simulations can be made to appear so much nicer.

Cross section of the SPHERIC 2 test case, with each SPH particle rendered as an appropriately-sized sphere.

The test case at 0.5 seconds: the water has just reached the obstacles, creating a splash.

If when you execute `paraFoam` in #OpenFOAM you get `paraview: not found` and you could not repair it, you can create a `.foam` file via `foamToVTK` and save the output to a .foam file and open it via #paraview.

#LetsLearnOpenFOAM

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.

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.
