Q. I am running an MFX case that successfully transfers the loads from CFX to ANSYS. However, it looks like the displacements are not coming back to CFX, since the mesh doesn't move. What could be wrong?
A. It is possible that all the nodes on the interface are also part of a boundary which is not allowed to move. This could be the case, for example, if the model were a 2D representation one element deep with Periodic boundaries. You can either create symmetry boundaries instead, where the motion is Unspecified, or edit the CCL of the periodic boundaries to become Unspecified (CFX-PRE won't let you make the mesh motion of a periodic boundary Unspecified).
