User fortran: Transiet boundary simulation

Casper_07 · May 10, 2016, 03:10

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 and outlet are my periodic boundary condition (single phase flow but multi fluid flow) to the CFX model. Should I write User Fortran code for controlling switching boundary condition? Can I use CEL expression to do it?

You can use a fortran routine to evaluate a CEL variable. Have a look in the documentation for how to do this.

Will you share some tutorials? if you have it

They come with CFX, so no need to share it as you should already have it. They are copyright anyway so I cannot share them.

If you did not install them then do a reinstall and put them in.
