Merging of disjointed meshes
Greetings!
I'm trying to generate a mesh by combining 2 extruded ones with different number of layers, resulting in an interface between them where elements will not be connected. When saving the result as a .msh file, the resulting element list says that some elements have 0 index nodes. I've also tried to operate on the new set by elevating it to 3rd order, but gmsh gets very confused and mangles some element faces. My questions are:
- is it possible at all to what i want?
- could this be done in a single .geo file using 2 extrusions? I've tried, but it just kept eliminating the interface.
The whole point of this is that we need full 3rd order hexahedra meshes on our code, even if the mesh contains hanging nodes. Please, find attached the files that I've been using so far, as well as a picture of how it should look like.
In any case, thank you very much!
