Hi folks. I’ve generated a human head model (with brain). I’m trying to mesh it with sculpt.
I took the following setting:
sculpt volume 1 15 size 0.0058 box location position -0.11 -0.14 -0.15 location position 0.11 0.14 0.15 void 1 gen_sidesets 2
The result is fine, but I hope to increase the mesh quality furthermore, especially at the interface between head and air(around the nose). I tried several pillow and smoothing options but they don’t give a better mesh. Is there other way to optimize my mesh? I hope the element size is kept above 0.005.
head_model_final.cub5 (4.3 MB)
There’s some nonphysical fields around the nose in my simulation. I guess it might related to the mesh there. Of course it might be caused by paraview’s post processing as well.
Hi @WayneYY,
have you already tried some refinement?
For a coarse mesh the quality is already good. I would at least try to refine at the interfaces.

If you need a smaller element count then you can try to choose a bigger element size as it will be refined at the interface surfaces anyway.
