    Improve Tet mesh quality - Cube with multiple spheres

    Thanks Mustaine3 for your suggestion. I did run a test and it seems to be good although with element distortion warning. Btw, Can you explain more about "be careful with linear tets"? I still don't understand your warning about C3D4 element? Thanks.

    Improve Tet mesh quality - Cube with multiple spheres

    Hi All, I am working on modelling of a cube with multiple spheres which induces extremely complex geometry. Using free mesh provided in Abaqus, I am able to generate the tetrahedral mesh (C3D4 element However, it is very bad quality mesh, there are many distorted elements (~500 element). I...
