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 BuddyZ |
