A question about how to define heat flux on wall boudary
 
Hi dears:
I'm thinking about how to add constant heat flux as boundary condition on just a part of the whole wall, have you guys done that before?
Cheers

Yes, it is easy. I presumed that you have the energy solver.
it is just enough to go to the wall and open the Physical Condition. Under Physical Condition, click on thermal properties then you can select the heat flux choice.
again under the wall/Physical value, give the desired heat flux.
good luck

When you want to specify the heat flux only partially, just create an appropriate field function and apply it to the wall. I think, you should get some examples how to do that from the user guide.
And yes, I've done it before. That's no special trick, it's everyday business.
