Dynamic mesh - structured mesh
I'm doing this 3D simulation which involves the movement of one of the walls of the object, and for this I'm using the dynamic mesh capability of Fluent.
Here I'm enabling smoothing and also the hex mesh smoothing (which worked perfectly for the 2D simulation). I'm also setting up all the adjacent zones to the moving wall as deforming zones, with smoothing and remeshing enabled.
However, when I start checking the displacement with "Mesh Motion" I can see that the mesh is not displacing what will cause eventually negative volumes. I used this same configuration for an unstructured mesh and it worked perfectly, but I don't know what extra parameters I should set up in order to have the mesh updating at every time step.
