[blockMesh] Circumferential refinement mesh on the outside of a concentric cylinder geometry

charryzzz · April 23, 2021, 00:26

Hi Foamer!

I have a question regarding generating a mesh in which different blocks have different cell number in the same direction, see the attached figure.

The diameter of the inner circle is 2 mm, and the outer circle has a diameter of 100 mm, 50 times larger than the inner one. Therefore, I need to give more cells in the circumferential direction of the outer circle. I don't have a clue to solve this problem now.

Is there any similar tutorial or example similar to this setup available?

Any suggestions or even the solutions will be appreciated

Mesh the inner cylinder and outer annular geometry as separate unconnected regions. Then, couple these regions using ACMI patches.
