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?
