Non-positive volume detected cells in FLUENT, blocks orientation

Dear all,
I have done a 3D hybrid propeller (only 1/4 of the geometry) mesh with Pointwise (the rotating part structured, outer box unstructured, 250.000.000 cells) and I am having some troubles with the hybrid inizialization with Ansys FLUENT. I can import the mesh and then do the setup (MRF, not sliding mesh), but when I begin the hybrid inizialization it doesn't go on. I have a warning message on the console "1138109 cells with non-positive volume detected", and I think the problem is the orientation of the blocks in Pointwise. I checked that and I have a right-hand rule for the orientation, but maybe there are other rules that I don't know of. Can you help me ? Thank you, E.G |
