Prof. Ghristophhe, thank you for your tip! Right now I have tried it but I have obtained the following errors:
Error : No elements in region 2 Info : Done meshing 3D (0.005192 s) Info : Optimizing 3D mesh... Info : Optimizing volume 2 Info : Done optimizing 3D mesh (0.00019 s) Info : 537 vertices 1236 elements Error : ------------------------------ Error : Mesh generation error summary Error : 104 warnings Error : 105 errors Error : Check the full log for details Error : ------------------------------ In any case, this idea is very good. In spite of this, I would like to know if it is possible to replicate this case only with tetrahedra, in this way I can avoid using different base functions in my finite element code. Best regards O.
