New Animation Request

[fortoboy]

Hello,

I was wondering if you could help me write a new Animation case that applies a normal force to the surface nodes of the mesh.
The algorithm would go something like this:

1. Calculate normals at either nodes or elements (then average them in 1 ring to get at nodes)
2. Apply a prescribed magnitude force at each node on the external surface in the normal direction
   The use case is that I want to apply both an internal/external pressure to a cylinder

Obviously, this is an enhancement and just looking for some help
