user fortran: boundary conditions-transient simula

Vanessa

Dear all,

I want to couple a fortran model with a CFX model. In my case, my fortran model will provide the boundary (time varying) conditions for my CFX model. I've been through the documentation but I find it confusing. In my case the inlet velocity is my boundary condition to the CFX model and I should return to my fortran model the pressure (as I said before both models are coupled). Several questions arise: 1) I am too confused with the whole interaction within each time step (input output variables, stacks, etc.) and 2)how do I return to my fortran model the information from my CFX model?

Thanks

Vanessa
