How to use FEM mesh boundary layer?

Hellow All!

How to use FEM mesh boundary layer?

I created one cylinder (or cube, never mind)

When I create a mesh by Gmesh and add boundary layer, it ignored. (min/1st thickness = 0)

If I set minimal size of layer to some values I get the error
0.3: Error : ...\fcfem_cyudtyjo\shape2mesh.geo', line 12 : Unknown option 'hwall_t' in field 1 of type 'BoundaryLayer'
Error : ...\fcfem_cyudtyjo\shape2mesh.geo', line 14 : Unknown option 'FacesList' in field 1 of type 'BoundaryLayer'
Warning... (warning is never mind)
And mesh is not created. :(

There is only one person ever who used boudaray layer AFAIK, its developer ... Hope the following two topics help more in this regard.

issue #3111 find links to various boudary layer topics over there

https://forum.freecadweb.org/viewtopic. ... 88#p336288

If you have any examples, tests, ideas, bugs to fix in the regard of boundary layer just go ahead and give information.

cheers bernd

BTW: on the contrary, mesh groups and mesh regions are well tested and widly used!
