The model becomes rough #151

Closed wjsjtu123 closed 7 months ago

wjsjtu123 commented 7 months ago

I imported the exact smooth stl model file, then during the simulation I found that the original smooth model became very rough, this should be related to the resolution of the simulation, I would like to ask if I increase the VRAM so that my model will become smooth.

Hi @wjsjtu123,

the roughness is expected as the model is voxelized to the Cartesian LBM grid. This is related to the grid resolution, and the stairsteps will get smaller with increased VRAM size. See issue https://github.com/ProjectPhysX/FluidX3D/issues/149.

Kind regards, Moritz
