Does anybody know how to get the values of Gas Constant, Especific Heat, etc, through RP_Get_Real command and/or where can I to find more information about this?

Its too late, but someone else could benifit
First you need to create a scheme variable by typing in the followong command in either the fluent or in a file fileName.scm and reading it from Menu->File->Read->Scheme...

(rp-var-define 'gas-constant 8.314459 'real #f)

Then you can use the following command in your UDF file which should then be able to access your variable named gas-constant defined in scheme.

real R;
R = RP_GET_REAL("gas_constant");

you can use as many values in your UDF as you want with same procedure

It did.

P.S. I think the UDF must be Compiled not just Interpreted.

Thanks
