Constant heat flux as BC

Post by fomeh »

Hello,
I don't find how to impose a constant heat flux BC on a wall. Thermal module is activated for degC neverthless, in BCs definition, all availble options own degC unit.

Hello,

I may not be the best guy to answer this but I do not think that this can be done via the GUI. I think you should use a user subroutine called "cs_user_boundary_conditions" where you will specify "non standard BC's". This is well explained in the user manual §6.4.2 as I leanrt to do it with this manual.

Hello,

Actually, you can prescribe a constant flux with the GUI, using the "Prescribed Flux option".

The field to which it applies is "TempC", but the units (not mentionned) are standard international units, so that is Watts per square meter.

Regards,

Yvan
