Mesh Initialization
 
Hello, I was wondering if someone could tell me what mesh initialization procedure is? I received the following message from gambit while meshing a volume with tgrid: "Initialization failed, perturb boundary nodes and try again" although the mesh was created and read into fluent 6.1 successfully, Is anyone know what the meaning of all that? Can I continue with my simulation despite gambit message?

Many Thanks

Re: Mesh Initialization
 
You have to check the grid. Use the "Examine Mesh" feature in Gambit. Look for maximum equi-angle skew. It might be too high. There's also a check-grid function in fluent, but that will only tell you if there's negative volume cells (which are very-bad, and Fluent won't even let you run if it finds any). Also, use some of the planar cuts in the examine mesh feature to make sure there isn't anything weird going on with the mesh.

Good luck.

Jason
