User Defined Real Gas Model
I need to model natural gas in a high pressure (6000kPa) pipeline. I believe that I need a user defined real gas model to do this.

I am looking for code for such a model. It can be Peng-Robinson Equation of State or Redlich-Kwong EOS or similar.

If anyone has this udf, or knows where I can get one from, I will appreciate it a lot.

A UDRGM for methane would be just as helpful. Actually, a UDRGM for any gas will be great. I can always modify it for my needs.

Thank you all in advance.

these equations are available in the material properties of fluent..
just check under density and you will find Peng Robinson equation of state..
All the best...
