  3. When I set up a mixture material with the NIST Multicomponent Real Gas model, Fluent fails with the error: “Error: REFPROP_error (117) from function: setupn[SETUP error 117] TNo mixture data are available for one or more binary pairs in the specified mixture. The mixture is outside the range of the model and calculations will not be made.”

      Despite its appearance, this failure is actually due to a known limitation. It is documented in the Fluent User Guide as follows: “For mixture flows, not all combinations of species mixtures are allowed. This could be due to lack of data for one or more binary pairs. In such situations an error message generated by NIST will be returned and displayed on the ANSYS Fluent console, and no real gas material is allowed to be created.”
