Hi @klausbu, I don't have a ship hull sample on hand but feel free to try it yourself! To your questions: 1. FP64 arithmetic is neither required for LBM nor...

Hi @zrosol232, what does the console window (switch to it with Alt+Tab) say in the failed case? I assume you have the A770 8GB model? Could it be an issue...

Hi @zrosol232, this seems a problem with the `.stl` voxelization kernel. Can you attach `Full_Pack_21700_Rev2_SMALL.STL` so I can reproduce? Thanks and kind regards, Moritz

Hi @zrosol232, this is strange, it works for me with 7GB VRAM occupation. EDIT: I tried again with the newer 4953 drivers, and it also works. 

@zrosol232 driver issues are much more likely. Arc is very picky when any components from old drivers are still present. Try removing all graphics drivers with [Display Driver Uninstaller](https://www.guru3d.com/download/display-driver-uninstaller-download/), Intel...

Hi @zrosol232, I've [fixed a bug](https://github.com/ProjectPhysX/FluidX3D/commit/d55be40ffcc62321b111dfa79c707638d9ccd8bd) in the voxelization kernel recently (PR #101), which was an out-of-bounds register access that could potentially cause crashes or freezing. Although Nvidia and Arc...

Thank you so much! I have uploaded a few more interesting devices :) Unfortunatley there is problems on some platforms that I have tested. I either get `Segmentation fault`, or...

Hi @jackwei86, thanks a lot for reporting this! I have [fixed](https://github.com/ProjectPhysX/OpenCL-Wrapper/commit/f5113b2a9a1e15719d1de92b9548bb31c92b50ac) it by disabling zero-copy on ARM iGPUs. Kind regards, Moritz

Hi @JablonskiMateusz, I am observing that on Intel UHD 630 (i7-8700K) with driver 31.0.101.2134 (Windows), the `__opencl_c_integer_dot_product_input_4x8bit` and `__opencl_c_integer_dot_product_input_4x8bit_packed` feature macros are both present, despite lack of dp4a support. How...
