Define_Profile() position in loop
 
I'm not sure about the position of Define_Profile() position in the Solution Procedure loop.

Is it executed at the same time as Update Properties macros past Solver and before Define_Adjust() macro?

What would happen if for instance the temperature of the same zone is set in Define_Profile() and Define_Adjust() macros? Which values take effect?

The User-Defined BCs (where you use the DEFINE_PROFILE macro) are applied at the "Update Properties" step.

Convergence is checked after this "Update Properties" step and then the next loop begins.

The DEFINE_PROFILE values would be used for the convergence check, and then the DEFINE_ADJUST values would be used for the solver step of the next loop.

Thank you 'e'

I needed a decisive answer. But one more question. The step: "Update Properties including User Define Properites" seems a very broad expression. I suppose most macros excluding General Purpose Macros are comprised in this step? Am I right? Is Define_Source() also included here?

Source terms are applied (with the DEFINE_SOURCE macro) at their respective equations. Momentum source terms are applied when the momentum equations are solved, energy source terms are applied when the energy equation is solved etc.

Thanks a lot 'e'
