Hi @jasonxauat, particles on multi-GPU require a lot of extra logic to determine which particles move between GPU domains and have to be copied over in between time steps. There...

Hi @jasonxauat, that approach sounds very reasonable. The memory overhead isn't even that bad - it could happen that all particles move from one domain into another, and then no...

Hi @jasonxauat, I have finally done the multi-GPU particles implementation. Your general approach was very good already, but some changes were still needed and some more optimizations were possible: -...

Hi @Afei2021, have you enabled the [`SUBGRID`](https://github.com/ProjectPhysX/FluidX3D/blob/master/src/defines.hpp#L24) extension? Kind regards, Moritz

This is simulation instability. This F1 geometry is difficult, with tiny gaps between the front tires and front fenders, and erreneous placing of the right back wheel. The model needs...

Hi @MGRAFF2006, I'm sorry that the first thing you see is something not working. Let's get to the bottom of it. Thanks for already providing the reproducer! I need some...

Hi @MGRAFF2006, is this issue resolved for you? Kind regards, Moritz

@MGRAFF2006 @ikozyris which exact iGPU from which CPU, and what driver version is it? Does it still show the artifacts with the latest Intel iGPU driver?

@lk251 what you posted is a different issue. This happens when the mesh is not watertight, meaning there is holes or overlapping triangles. There is software to fix such meshes,...

@MGRAFF2006 the iGPU has no dedicated memory, it just uses shared RAM. The RAM speed is not the issue - if it's slow than it will just take longer, but...
