Hello,


in a simulation, I work with a dynamic mesh. Unfortunately, the number of cells increases over time (possibly also by improving the mesh quality, which also consistently worsens).

I have tried to combine small cells via mesh adoption, but apparently still have a thinking error.
If I set as Coarsening Criterion.
- CellVolume<1e-10[m]^3, 0 cells are marked. If I enter
- CellVolume>1e-10[m]^3, also 0 cells are marked.

If, on the other hand, I specify for Refinement Criterion
- CellVolume>1e-10[m]^3, 2960485 cells are marked (all).

Perform MeshCheck says:
Volume statistics:
minimum volume (m3): 3.370395e-12
maximum volume (m3): 2.538826e-04

Can someone explain me the behavior or tell me what I can do so that I can combine small cells?


Thanks a lot
Aemon
