Dear Gmsh community,
Do you know how to force gmsh to produce only one layer of hexahedral elements
through the thickness of the thin-walled structure like in the attached
example? I want to have only one layer of linear elements which will be than
converted to higher order spectral element type.
3D meshing always produces two elements even though 1 layer is set in extrude
operation.
You get 2 elements in the layer because of the
Mesh.SubdivisionAlgorithm = 2; // 1: all quadrangles; 2: all hexas
command, which subdivides the mesh (to get a full quad/hex mesh).
There's active work on new quad meshing tools, so hopefully this limitation
will disappear in the future.
