Hi, I am pretty new to GMSH and I am trying to create compound surfaces to mesh several elementary entities (surfaces) of my geometry as one surface. The goal is basically to avoid degenerated triangles on very narrow surfaces by merging them together. Here is my code:

Unfortunately I get the following error messages:

I am clueless about what it means since the 'unknown' surfaces are
recognized and meshed properly with no error when I don't use the compound
surfaces.
Can someone tell me what is happening and how to use Compound surfaces?
If not, does anybody know of an other way to obtain the desired result. I
attached the matching .geo file for more clarity.
Thanks.
