[Gmsh] Mixe of structured/unstructured mesh

[Rémy Bretin]

Dear all,

I would like to mesh a small cube merged in a bigger cube: the small cube having a structured brick mesh (50x50x50 elements for example) and the bigger one filled with a coarse unstructured mesh (making a gradient from the small cube to the edges of the big cube)(the element type doesn't matter, but I guess it should be Hexa mesh). I have been able to realize that kind of mesh using ANSYS APDL, but it generates pyramidal elements that don't exist in ABAQUS (which is the solver I use). I've tried with GMSH to see if there is another way to mesh this but without any success.

Here is an example of what I would like to get (obtained with ANSYS APDL):

Thanks in advance for your help!

Rémy
