How to create peristicaltic flow with grid deform.
 

I used CFD to create peristicaltic flow in a tube. For X direction, i applied velocity and then gird deformation with sin. Y direction on the top is just grid deformation with all free and Y direction on the bottom is axi_symetric..

If does anyone have idea of creating grid deformation for peristicaltic..

Please email me..
