Combination of transfinite meshes and full-quad recombination
I got a simple test case with two concentric rings mesh_test.geo. The inner ring should contain a transfinite mesh (e.g. to resolve a boundary layer) and the outer ring a full-quad mesh. Since the progression in the transfinite mesh is subdivided if I activate subdivision, I tried to use the full-quad blossom recombination in this setup. However, I get the following error:
Info : Meshing 2D...
Info : Meshing surface 1 (Transfinite)
Info : Meshing surface 2 (Transfinite)
Info : Meshing surface 3 (Plane, Delaunay)
Warning : Full-quad recombination only compatible with transfinite meshes if those are performed first
Error : 1D mesh cannot be divided by 2

Error : 1D mesh cannot be divided by 2
Error : The 1D mesh seems not to be forming a closed loop (8 boundary nodes are considered once)
Since I am new to gmsh I might need some explaination on the error. Is it generally not possible to combine transfinite with full-quad recombination or did I do something wrong in the setup? FYI: This type of mesh should be generated around an airfoil with a tool using the gmsh python api
later on.
