Very simple moving mesh

Pete

Hi there,

I need to create a very simple moving mesh to test out the function. What I would like to do is create a 2D axisymmetric laminar pipe flow mesh with two halves, and allow the mesh to deform over time, much like this:

Then I would like to compare the results from this to that of a non-deforming mesh. Can this simple moving mesh be created without the use of a UDF or do I need to write one? Perhaps there is a simpler way for me to obtain a moving mesh?

Any help/tips/comments would be greatly appreciated!
