overset running blow up

OREOMax · June 26, 2021, 03:35

Hi,guys

I am struggling in a overset problem.I've check my mesh several times and I think its ok.celltypes,zoneID,overset almost anywhere are exactly the same just like the tutorials.

But my running is still blow up,first I try overInterdymfoam,copied fvschemes and solutions for my own case,also the 0/initial alpha.water,p_rgh,U and so on.

Then I try overPimpleDyMFoam and remove alpha.water,all settings follow the wolf dynamics overset tutorials --flapping aerofoil.
