Default wall velocity in remeshing case

Dear all,

I have a problem in solving the route of body falling freely in the air. I use remeshing for simulation. When I want to apply wall velocity on the body, the solution is not impossible and causes the error. The reason is that I defined a variable for wall velocity. I think that the wall velocity can not accept variable because, when I give the expression for wall velocity there is no problem. I am forced to use variable for wall velocity. Is there any solution for it.

Thanks a lot

Can you explain what you are doing? What is the falling body? What path do you expect it to take? Please attach an image.
