Can I alter the field static pressure using UDF?
 

Hello all,
I know that C_P(cell, thread) will call the local static pressure variable into the UDF for each cell. Is there any way by which I can alter the local static pressure? Something like a macro. For example, If I want to introduce a pressure correction in momentum equation, is there a way to do that with or without UDF? :confused:

Hi Anuarun,


Not really, not in Fluent. The Fluent solver is continually trying to get pressure and velocity to match, so it will fight against any unexplained variation to pressure. I think if you want to explore the details of solver numerics, OpenFOAM might be a better option.


Good luck!
