Hi,

I am trying to do a problem in CFX v12.1 where density as a function of Pressure and Temperature.
Can anybody help me how to input this in CFX.

Presently I neglected Temperature effect and wrote a CEL Rho = Rho0/(1-(P-P0)/BulkModulus)). It gave some satisfactory result. But I really want to model the complete density variation with pressure and Temperature.

Additionally, if I use Rho as a CEL variable as said above, I could not use Total energy model. It runs only isothermal. Any clues ?
