### 12.5.1. Properties

If you use your own RGP table and at any point during the solution, the temperature or pressure falls outside of the range in the table, you will receive a notice from the CFX-Solver that it has clipped or extrapolated the value and that the calculation will continue. For example, this may occur during the first few iterations as the solution begins to settle down from the initial guess. If the messages do not persist then you can safely continue with the solution. If these message do persist, then you should generate a table with a larger pressure and/or temperature range.

Pure substances that use real equations of state (non-ideal or non-constant density) can be used in the same way as any other material in CFX. They can form components in multicomponent fluids or be used in multiphase simulations.

You cannot specify mixture properties for homogeneous binary mixtures.

All boundary condition specifications use real fluid relations for conversions from total to static conditions.
