How to control the mesh size when using an stl file
Hi,
I am using gmsh4.6.0. I would like to make a volume mesh from a closed surface coming from an stl file. I don't manage to choose the mesh refinement in order to have a coarser mesh than the one of the surface. When I change Mesh.CharacteristicLengthFactor, I still have the same number of elements... I tried using Mesh.CharacteristicLengthExtendFromBoundary = 0;, Coherence Mesh; and CreateTopology;, but nothing is working. Do you have any idea what I can do to be able to tune the elements size ?
You can find attached my stl and geo files.
Thanks a lot for your help,
Cécile
