Problem with deforming mesh

Roland R · February 21, 2011, 12:50

Dear CFX Users,

I would like to complete a simulation with deforming mesh. As far as I know, in CFX Pre I can define displacement to the boundary conditions only but I would like to define the mesh displacement to the full domain (to all nodes). I tried to define the movement to all bondaries which are placed around the domain but based on the results this solution is not correct because there are a lot of nodes in the center of domain which don’t move exactly with the boundaries.

Can anybody help me?

Thanks in advance:

Roland

Create a subdomain and move the subdomain.
