Hi, I'm meshing for a 10-cell fuel cell stack, first I generate face mesh using blocks,then I can get the mesh in the middle by extruding mesh to form the 1-cell mesh and translating and coping mesh,and I need to get the mass flow of each stack.,so I create some iso-surfaces parallel to outlet,but I find there are some elements missing on the face and I'm confused. This will lead to inaccurate mass flow calculation.Does anyone know how it works?

I don't know if this helps, but when I see something like this in ICEM, mostly the problems are related to the normal of surface elements not being consistent. You can change this in the edit Mesh Menu > Reorient Mesh > Reorient consistent.
Just select one of the elements as a reference. It does not matter which one. In the end, at least all elements for each boundary have the same normal and are in one group in Fluent. |
