non uniform heat flux

Hello all,

I'm trying to model simple 2D conduction model in a slab. What I want to do is use a non-uniform heat flux for a boundary condition. I already have the heat transfer coefficient distribution along that boundary, which is a gaussian type distribution. Instead of using a gaussian distribution I would prefer to actually call a file that will assign the values of the heat transfer coefficient along the boundary. Do you know if that is doable?

Thanks,
Anastassis
