The pressure in my calculation domain can change from 100Pa to 0.1Mpa,so the physical properties vary with pressure. If I choose a real gas model for the density of air, how should I set the other physical properties besides UDF ?

Each property has its own EOS. You can use real properties for density and still use constant properties or arbitrary for everything else.

Which properties are you discussing? What would you like them set to? Why is the word UDF even being mentioned at all?

Thank you. I want to set the specific capacity, viscosity and thermal conductivity as a function of pressure.
