[Gmsh] R: Problems with 2D mesh

[Alessandro Vicini]

Hello Christophe,

the surface mesh is wrong if you set Mesh.CharacteristicLengthExtendFromBoundary = 0. I have just tried latest version 4.0.5, but the behavior is the same…

With the attached geo file (TestCase) I have a problem in the 2D mesh of some of the internal faces (see attached picture) if I set Mesh.CharacteristicLengthExtendFromBoundary = 0 (which is what I would like to do), regardless of the meshing algorithm. The mesh is ok when
Mesh.CharacteristicLengthExtendFromBoundary = 1. I'm using v4.0.1. Is there a way to solve this? Thank you.

The mesh size looks OK to me given your mesh size field (I've tested with Gmsh 4.0.5):
