zjbwow is on a distinguished road
hi there,this picture below is the BC I set in the gambit.
the left line is the pressureinlet and the right is pressureoutlet.in the sets of define-dynamicmesh-zones,I set default interior,fluid,bulletwall as rigid body and wall,inlet,outlet,axis as stationary.
but when running the mesh motion the error message comes up:
Updating mesh to time 1.00000e-04 (step = 00001)
Mesh Statistics:
Min Volume = 1.50000e-07
Max Volume = 3.50000e-07 Done.
Updating mesh to time 2.00000e-04 (step = 00002)
WARNING: non-positive volumes exist.
Mesh Statistics:
Min Volume =-5.00000e-08
Max Volume = 5.50000e-07
Warning: negative cell volume detected!
Error: Preview-Dynamic-Mesh failed
Error Object: ()

how can this happen?
what should I do?
thank you
