Dear OpenFOAMers,

During the SnappyHexMesh, some informations appears. For example:


Shell refinement iteration 2
----------------------------

No cells marked for refinement since reached limit 2000000.
Determined cells to refine in = 8.23 s
Selected for internal refinement : 1555 cells (out of 3033385)
Edge intersection testing:
Number of edges : 9928941
Number of edges to retest : 133749
Number of intersected edges : 692286
Refined mesh in = 36.57 s
After refinement shell refinement iteration 2 : cells:3044270 faces:9928941 points:3851359
Cells per refinement level:
0 21480
1 14552
2 26210
3 77440
4 301465
5 666257
6 1936866


I have two questions about these messages:
1) what happens if the limit of cells is reached? Is there any problem? (In my case I have a limit of 2000000 in the snappyHexMeshDict).
2) what does it means "out of 3033385"

Is there any OpenFOAMer that knows these questions?

Thanks in advance,
Elisenda

Hi nothing happens if the cell limit is reached it will just stop refining. So if you need further refinement you need to up the cell count.

what does it means "out of 3033385"

it just means that 3033385 cells match the refinement parameters and have been selected for refinement.

Thanks a lot Linnemann.
