Hi,

I would like to use temperature varying properties for viscosity and thermal conductivity while assuming the fluid to be an ideal gas. I am using the compressible 'rhoPimpleFoam' as the solver. I wonder if we can do that ! I tried it and it gave the following error:

------------------------------------------------------------------------------------------------

Selecting thermodynamics package hPsiThermo<pureMixture<polynomialTransport<specieT hermo<hConstThermo<perfectGas>>>>>


--> FOAM FATAL ERROR:
Unknown basicPsiThermo type hPsiThermo<pureMixture<polynomialTransport<specieT hermo<hConstThermo<perfectGas>>>>>

Valid basicPsiThermo types are:

11

ePsiThermo<pureMixture<constTransport<specieThermo <eConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<eConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<hConstThermo<perfectGas>>>>>
ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<janafThermo<perfectGas>>>>>
hPsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>
hPsiThermo<pureMixture<sutherlandTransport<specieT hermo<hConstThermo<perfectGas>>>>>
hPsiThermo<pureMixture<sutherlandTransport<specieT hermo<janafThermo<perfectGas>>>>>
hsPsiThermo<pureMixture<constTransport<specieTherm o<hConstThermo<perfectGas>>>>>
hsPsiThermo<pureMixture<sutherlandTransport<specie Thermo<hConstThermo<perfectGas>>>>>
hsPsiThermo<pureMixture<sutherlandTransport<specie Thermo<janafThermo<perfectGas>>>>>
)

------------------------------------------------------------------------------


It seems polynomial temperature varying properties for viscosity and thermal conductivity simultaneously is not an option ! Is there a way I can do that !

Thanks much for all the help.

Or is it possible to use 'sutherlandTransport' equations for both viscosity and thermal conductivity in the same problem setup ! Then I can use temperature varying properties for both provided I am able to do a good fit for thermal conductivity !
