[mesh manipulation] Mesh refinement

dumas · June 30, 2015, 14:31

Hello users, I have a problem if I'm simulating the wall when there boundary layer concentration, I need to refine the mesh. In the case it would be in the top wall and outlet. I am OpenFOAM 2.3 user. If anyone can help me I will be very grateful. Attached'm leaving the mesh created.

Best regards.

Hi,

sorry for the late reply. Maybe it's still useful (either for you or for follow-up readers).

I believe this can be done with two rather simple steps:

1. define the cell region nearby the the desired patch using topoSet or setSet
2. refine the mesh regions defined in the previous step using refineMesh (usage of a refineMeshDict, see https://openfoamwiki.net/index.php/RefineMesh)
