For the options that control the mesh quality and size, see the documentation page of DiscretizeRegion. It works essentially the same way. In particular the option MeshRefinementFunction is o interest.

The element type can be selected with the option "MeshElementType". Some (but not all) possible values are "QuadElement", "TriangleElement", "HexahedralElement", and "TetrahedralElement". Currently "QuadElement" and "HexahedralElement" won't be available for must input geometries since it is actually quite hard to generate such meshes with high quality.

| May 3, 2019 at 18:19 | comment | added | Gustavo Meyagan | @Hendrik Schumacher quick question: what options can I use to enforce a regular mesh size (i.e. all mesh elements should have the same size) And how can I change the form of a mesh (i.e from triangle to quadrilateral)? | |
| May 3, 2019 at 10:50 | comment | added | Henrik Schumacher | Hm. I hope you use Neumann boundary conditions on the large planar surfaces of the of the thick plate. Then one could model the heat flow on the thick plate by a heat flow on the thin plate with interior heat source proportional to <<Neumann boundary condition on top surface>> - <<Neumann boundary condition on bottom surface>>. Do you understand what I mean? Maybe it would help me if you wrote down the exact PDE that you want to solve. | |
| May 3, 2019 at 10:24 | comment | added | Gustavo Meyagan | Thank you very much for your help! I actaully want to simulate heat flow for the given domain with prescribed boundary conditons on the surfaces of the region.Before I impose NDSolve however, I would like to control the meshprecission ,thus the reason why I wanted the visualisation of the domain beforehand. Unfortunately the layer of the domain is fixed (the context is 3D Printing). How do I proceed further from here? | |
