How to move an edge of a rectangle box in Fluent?

I have a box with 4 edges. I want to move an edge toward inner region and then the inner fluid region is condensed.


In fluent, I use a UDF to set v[0]=0.1, v[1]=0, v[2]=0. Set other 3 edges to be fixed. Zone type rigid body. However, there will be a negative cell error soon. See in the picture:


It looks like that original node in the fixed wall won't move when the moving wall is moving.


How can I reach my goal?
