I try to create the UDF for simulation of heat transfer in a meterial during impulse laser work. It look in this way:
1. laser on - heat flux defined at the boundary,
2. laser off - convection heat transfer on the boundary
3. laser on - heat flux defined at the boundary,
an so on ....

This repeats 50 times per second and my question is it is possible to write UDF to switch boundary conditions at the wall?
I know that this period of "laser off" can be neglected but this is what I want to show.

Any ideas?

Thanks in advance

I have never been using scheme programming. Are ther any suitable tutorials for this?
