Laser Pulse Heat Flux

Please login with a confirmed email address before reporting spam

Hi All
Im trying to model a laser pulse on the top of a flat plate to bond a plastic strip to it. I need the heat flux to be on for a certain amount of time and then turn off and get replaced by a convection boundary condition. How do I specify time dependence for the boundary conditions.
Thank you
Brendan
PS: Sorry if this question is insanely simple. My teacher just threw COMSOL at us and we don't have much time to learn it.
