[Gmsh] CopyMeshingMethod Problem

[Stefan Zörner]

The CopyMeshingMethod should preserve any transfinite information during 
copying (Duplicata).
I have the problem that if I want to copy an extruded surface the 
meshing data is lost and the new copied surface has the fallback meshing 
information.
Attached is a simple testcase. The "Duplicata" works prefectly on the 
original surface but not on the extruded one.

I am glad for any help and thank in advance!

Stefan
