I tried results>mesh and played around with the options fof luid mesh, partial mesh and solid mesh.
For example, if I check the option of fluid mesh and partial mesh, the partial meshes displayed the fluid and solid region. And a cut plot will only give me 2D view of meshes. Is there anyway I can display only the 3D meshes in fluid volume?
You're in the right place. Post a picture of what you are seeing and what you want to learn from displaying the mesh. Personally I use cut plots to tell me what is going on. It doesn't specifically show fluid or solid or partial but it is somewhat obvious.
