moving wall
 
hey you all, i'm trying to model a moving wall in fluent. the model is fairly easy. just a tube with an inlet and i want to make the other end of the tube a moving wall that moves with constant velocity in the y-direction. what would be the best way to model this? setting the boundary conditions for the wall to a moving wall, but witch zones need to be in the dynamic mesh? thanks WIm

Re: moving wall
 
If it is a simple tube that can be mesh with quad/hex the best thing to do is to use dynamic layering.

You just have to assign the motion with the DEFINE_CG_MOTION macro, and set a few dynamic mesh parameters as described in the online help (search for dynamic layering).
