Transient Thermal Simulation Issue

Folks, I am a bit stumped on the best way to simulate a problem that I have been given.  (Sw2012 SP2 x64)

 

The problem (simplified) is as follows.    A small diameter (relative to component) heat flux BC spot on a large component (not necessarily flat) is roughly circular in shape.  that spot has a maximum at the center and a minimum at the OD.  That spot traverses across the component in a manner that requires a transient analysis.  What is the best way to set this up in simulation?   

 

I can not seem to find a good way to put an equation for the spot that varies both in position and time into the simulation tool.  I can approximate the spot using split lines on the surface and fixed values with a transient equation applied, but that still does not get me to translating the spot across the part.   I suppose I can "grid" the surface with split lines and apply a time based curve to each spot but that would be excessively time consuming compared to the value of the simulation.

 

any help is appreciated

 

thanks

Greg
