GregorAlan New Member Gregor Alan Join Date: Feb 2016 Posts: 9 Rep Power: 10	Hi all, I am trying to use a temperature dependent ideal gas law for the density in the chtMultiRegionSimpleFoam solver. The reason why I can't use the normal ideal gas law option is because I have a polynomial equation for mu, thermal conductivity as well as Cp. I either have to use PengRobinsonGas or give a polynomial for the temperature dependent density (assuming constant pressure). Is there a way to have a negative power in this polynomial to effectively reconstruct the ideal gas law but then define it in the thermophysicalProperties? Kind regards, Gregor Alan
