Check your working directory in the cfx launcher. Make sure it points to where the def and ICEM files are located.

Does anyone know what mesh morphing actually is ??? A ppt on the ANSYS site talks about mesh morphing being used for large mesh deformation and to avoid re-meshing.I gives the example of ball valve and butterfly valve tutorial. My case is very similar to the ball valve.
But I cannot find any particular tutorial or theory on it ???

Thank you.

The CFX tutorial titled "Fluid Structure Interaction and Mesh Deformation" sounds like a good place to start. There are several other moving mesh tutorials which come with CFX.
