Openfoam meshing snappy hex mesh

R786 · June 24, 2023, 12:12

My mesh is stuck in iteration 0 as follows, and does not move beyond this, what could be the reason for this?

Edge intersection testing:
Number of edges : 1520000
Number of edges to retest : 40000
Number of intersected edges : 53747
Decomposition method none [1]

Refinement phase
----------------

Found point (0 0 0) in cell 0 on processor 0

Feature refinement iteration 0

There is very little information here, you might want to check out Guide: How to ask a question on the forums

What your post does tell me, is that you are using (0 0 0) as the locationInMesh, which is against several recommendations. The locationInMesh should never coincide with a face or a node during all meshing phases. Round values or integers are usually prone to hitting such an entity, depending on the geometry. So maybe using e.g. (0.0012 0.012 -0.021) already helps.
