Non-Uniform Heat Flux on Boundary

Hi Everyone,

I am relatively new to COMSOL and would like to know if it is possible to define an inward heat flux on a boundary as a non uniform distribution(ex. Gaussian). Specifically, I am using the heat transfer module where I can define a q0 for any exterior boundary, so is it possible to define the q0 as being dependent on my x,y boundary coordinates?

If this is not possible, is there any other way to define a non-uniform heat flux on a boundary?

Thanks for the help in advance!

Hi

Basically in Comsol, whenever you can enter a constant, you can also enter an equation (only a begin comment sign is missing) so if you want an expression such as Fx*x*(1-x) or whatever it's up to your imagination, define your constants in the Parameter (V4) or Constant (v3.5) section
