|Summary||0002832: interFoam: unstable when restarting a reconstructed case|
|Description||When restarting an interFoam case in serial after reconstructing a parallel run, the restart is not smooth. Same, when the reconstructed case is again decomposed again, and restarted in parallel. One can see this in the min/max alpha-values, and also forces a oscillating quite remarkable.|
If the face velocity field Uf is deleted, the re-start is smooth.
|Steps To Reproduce||1. Run DTCHullMoving tutorial for a short time (e.g. 0.1 s). |
3. Run in serial
4. Plot forces
||Does this problem only occur when restarting a reconstructed case or also when restarting a parallel run or a serial run?|
||The issue is reconstructPar treating all surface fields as fluxes and setting the sign according to the face orientation.|
||Only occures when restarting a reconstructed case. Is there any need for storing Uf?|
> Is there any need for storing Uf?
Same as phi in the static mesh case; formally these are needed to get an accurate restart but not critical.
