Exit Profile BC
 
Hi,

I wish to apply a static pressure profile BC at the outlet (which I am having from experiment). Is there anything similar to the 'specified inlet profile' option?
Thank you.

Regards,
Jyoti

No, at the moment you cannot specify a profile at the outlet.



If you are in for some small programming you can do this:
In the function BC_Outlet in the file CIncEulerSolver for incompressible flow, it checks if you have a pressure outlet. You could replace the constant value of outlet pressure in the line
Code:
P_Outlet = config->GetOutlet_Pressure(Marker_Tag)/config->GetPressure_Ref();

with some array with values that you define, or a function depending on the coordinates.

Thank you for your kind response.
I was going through the CTurbSSTSolver and CTurbSASolver routines, as my problem is a viscous, compressible one. I was going through the inlet profile portion therein and found that a bit involved and was so wondering about the possibility of any pre-existing exit profile BC.
Thanks again.
