kharmonic on high-poly meshes #134

Open qiqigit opened 2 years ago

qiqigit commented 2 years ago

I am trying to solve a biharmonic function on high-poly triangular meshes (200K~ polygons). However, mass matrices become NaN easily and kharmonic doesn't seem to produce the expected results.

I am wondering if it is possible to solve a biharmonic function on high-poly meshes with kharmonic function or other methods. Any suggestion would be appreciated. Thanks!

200k shouldn't really be a problem. NaN in the mass matrix sounds like degenerate elements or unreferenced vertices, though. Would need to see an example mesh to know more.
