Default Inlet as a prescribed displacement

Hello Everybody,

I have started with CFX a few time ago, and I still have some basic doubts. I would like to use a inlet not with a constant velocity (as the tutorial teaches), but as a prescribed displacement, that would be cyclic.

Is it possible? If yes, can anybody help me to do that?

Thanks!

Is it possible to use the idea of predefined mesh deformation proposed in this message below? If it is possible, can anybody indicate or advise me with some literature where I can find this procedures?

Thanks..

Hi,

You can do this using the mesh deformation defined by specified displacement. The remainder of the mesh is moved using a smoothing algorithm. Look in the CFX tutorial guide for some hints - the ball valve tutorial is the one to look at.
