Question on CFX user fortran: how to obtain variable value of a certain local

leizi · July 13, 2019, 06:44

Dear all,

I'm using CFX user fortran to calculate some additional variables. During each step I need to get the pressure and coordinate of a certain boundary, but it seems that the user_getvar do not returns the variable of a specified locale. Is there any other routines/functions that can help me do that?

Could you be more specific on what you are trying to achieve?

Are you coding a UserFortran CEL function? or a junction box?

For the former, the software will evaluate the UserFortran function on the locale of interest for the software; therefore, it is implied and no need to over-specify it.

Are you trying to gather the additional variable at a different locale from the one the function is called for? For example, the function is evaluated at an inlet, and you are trying to gather the variable at the outlet.

Sorry for the unclear description. I‘m trying to code a cel function, which is evaluated over the whole flow field domain but it needs the pressure distribution on a certain wall boundary.

I found it out. I had to make a Mointor Point in CFX-Pre with the Expression I defined. Than I can Monitor this Monitor Point during the run. Thank you very much.
