Create a transition zone between concentric disks
Hello to all,
I would like to able to create a transition zone in a geometry with 2 concentric cylinders. The smallest cylinder will have a structured mesh with 40 elements around the circumference. The larger cylinder should have 200 elements across its circumference. To achieve this I created a zone with unstructed mesh making the transition from 40 to 200. However I am getting problems generating the mesh.
Is this the best approach for making this? Should I just create a 2D geometry for the transition zone and ask to extrude? If so, will gmsh know to merge both meshes?
I have the script attachedsimplifiedDisk_3.geo
