User FORTRAN for Monitoring in CFX

jir2830 · August 19, 2015, 13:25

I am trying to create a way to calculate the percent of area above a certain velocity on a given plane and monitor that value in the solver manager while the run is still going. This is a calculation I've done in Post using defined planes, ISO-Clip planes, and expressions.

I've been looking at User FORTRAN and Junction Box Routines, assuming that is the approach I'm going to have to take, but after all the reading in the ANSYS help, I still need help.

I'm assuming that I will need a native face in the geometry to export information and feed into the FORTRAN code, since you can't create planes in Pre like you can in Post to calculate things on.

Any thoughts on how to export from a native face, the structure and types of Routines I'd need to the FORTRAN related to the solver, I think I have a good idea what the layout of the code to actually calculate everything will be. And then sending the value back to the solver in order to plot?

Any help, thoughts, or ideas would be much appreciated, thank you in advance.

How about:

T = if(u>10[m/s],1,0)

And then do an area integral of T over your surface.
