[mesh manipulation] Mesh refinement based on previous results

mgab · December 27, 2016, 15:37

Hi
is there a way to refine a mesh from the results (like velocity or pressure gradient) obtained from a past simulation?
(I'm not looking for AMR)
Thanks!

Hi,

I am looking for a way to do that too. My best guess up to the moment is that we should create one or more cellSets based on the values of a field, and then refine these cellSets using refineMesh or refineHexMesh. See this thread and this thread. I would be happy if someone could point out a more straightforward solution.

Best wishes,
Thomas

Hello Thomas, I found the second link helpful. I was wondering if you'd use the published cellSets that's generated by checkMesh in order to build the refineMeshDict file.
