Moving Mesh Problem

Rashad

Hello Dear ALL I had a problem with the moving mesh. In my problem i move part of the mesh by using layering method.my probelm is during meshing where i mesh over a two lines combining at the corner. at this point when i move the mesh this point also moves upto next node. Although both line are rigid walls. i want that this point should not move. I try different things to avoid this i also use sliding mesh at this point but problem persists.

I shall be very great full for the reply
