Error Message Properties of the moist gas are physically unrealistic

Issue:

A humidity analysis stops with the following error:

Error: Properties of the moist gas are physically unrealistic

Error: Humid properties are physically unrealistic. Saturated Vapor Pressure = %lf, Mixture Pressure = %lf. Need to raise the Ref. Pressure or lower the inlet Temperature


Solution:

Solution

The vapor pressure is greater than or equal to the absolute pressure. This is not a physically realistic condition, so the analysis stops.

To resolve this issue, increase the reference pressure in the Material Environment dialog or decrease the inlet temperature boundary condition. Either of these actions will reduce the vapor pressure.
