State point evaluation
 

Hi there,

I am trying to calculate with massfractions of the air with a user subroutine in fortran.

The problem is, how do I get the values for the temperature and the density OUT of cfx?

Then, I want to calculate som things and then I want to give back TO cfx the massfractions of the air for some species.

Therefore... thats the point right now. Please help.

Regards Mareike

Re: State point evaluation
 

You can do this with CEL expressions. Do you need FORTRAN for some specific logic?

Hi Cyclone. Thank you for your answer.

Yes, I need fortran! I have programmed about 30 lines which calculate the massfraction for a specific condition.

Is it possible to do this without CEL expressions? Just a linked code?

Hi Cyclone,

if you would solve this via the CEL expression, how would you do this? Maybe I can combine some things. Any idea? Many many thanks if you know an answer.

Hi there,

I have got a similar problem to solve. If anyone knows an answer... that would be great!
