I am looking for an example of how to use the hpolynomialThermo and polynomialTransport in the thermophysicalProperties file for rhoPisoFoam.

I have played a little with the other types (sutherlands, hconst, etc...) but I can't figure out what the syntax for the polynomial type. Unfortunately the User guide isn't very helpful, and I can't find any similar examples.

For example, I want to have air and I know the 7-coefficient polynomial for mu and kappa with polynomialTransport, but I try:

thermoType hPsiThermo<pureMixture<polynomialTransport<specieT hermo<hpolynomialThermo<perfectGas>>>>>;
mixture //keyword
air 1 28.966 //species
1003.82 0 //hConstantThermo
0.1 0.2 0.3 0.4 0.5 0.6 0.7; //this is the polynomial for mu
0.1 0.2 0.3 0.4 0.5 0.6 0.7; //this is the polynomial for kappa

but it gives a error about unknown basicPsiThermo type.

Do I have to do something to enable the polynomialTransport and hpolynomialThermo types for this solver (rhoPisoFoam)? Could somebody please proved an example for me?

Thanks,
Jason
