Hello all!

I want to create a moving heat source and perform a 3D transient HT analysis. In order to do that I created a UDF that defines a moving heat flux boundary condition with gaussian distribution. The thing is that I want to use this boundary condition only in distance R from defined center of this distribution. The rest of a surface should have only convection on it.

Is it possible to define changing of boundary conditions in a UDF? If not does anyone have any idea how to get this what I want?
