Hello, 

I want to add R134a in the fluent material tab but I am confused on one thing.  

If I get R134a properties from the Nist website or Refprop software and add properties like density, Cp, Viscocity, etc as a constant for constant reference temperature, say 258K.

Then during the simulation, if ansys temp rises or falls from 258K then how ansys will manage to calculate density, and conductivity values accurately? 

or if we add any material then we should always use polynomial functions etc?

Hello,

The properties will not be for any fixed temperature but for the range of temperature and pressure.
