Default Cooling Heat Flux

Hi!

I am trying to set a heat flux on a wall. The thing is, this is not a warming but a COOLING flux, so it is supposed to REMOVE energy. I guess that, to do so, I should set a NEGATIVE heat concentration (-100 W/mē for example).

But when I do that, I have a divergence in the calculus.

If I set a positive value, this is working fine, but I do not want to heat my flow, I want to COOL it.

So? What should I do?

Thanks!
