[cfMesh] Preserving boundary integrity

celestial · November 7, 2019, 17:50

Hello to all

By integrity I mean the set of faces on the original triangularization of the boundary must be a subset of the faces of all generated tetrahedrons and of course no tetrahedron can extend to the other side of that same boundary.

Is cfMesh able to guarantee that for all physically meaningful 3D geometries ?

Does keepCellsInserctingPatches and removeCellsIntersectingPatches have anything to do with this boundary recovery ?

If you are as keen as I am in preserving boundaries after computing a mesh, run Gmsh, import your .brep geometry file and click 3D under Modules/Mesh. Guaranteed integrity regardless of the element size.
