Change the position of the force

The problem I try to solve is following.
I have a solid block with circular curve on face boundary. Then I define a force starting in point 5 (see attached file) in radial direction (which is Z direction in Point 5). Now with time changing I need to change the position of the force along the circular curve, keeping the radial direction. So it may look like clock arrow moving in YZ plane, for specific time my force pointing in radial direction but moving along the curve.
The robust way to do it is to define lots of points on the curve and step function, so that for specific time force will be acting only in one point.
But I bet there should be more clever solution.
I hope the problem is clear enough.
Attached is a model file.
Thank you.
Artem

here is one way (model in v4.1.0.185), but I have a little issue with the normalisation of the gaussian ;)

Good luck
