Sliding Mesh
 

Im trying to find out information on how to apply sliding meshes to a model i have constructed. The mesh has an interface bc into a tube, but slowly, the entry to the pipe is covered so the flow is restricted.

I am using cfd ace, and the sliding mesh problem is similar to the "sliding mesh with arbitary cell face matching" which is seen on the cfdrc website used in the moving piston application.

If anyone can help in anyway, it would be really great to hear from you.

Thanks.
