I have a simulation that works fine with I pick constant density as the physics model. But when I change it to real gas or ideal gas I get this error message:

Error:
A floating point exception has occurred: floating point exception [Divide by zero]. The specific cause cannot be identified. Please refer to the troubleshooting section of the user's guide

The other physic models I am picking are:
Space: Three Dimensional
Time: Steady
Material: Gas
Flow: Segregated Flow
Viscous Regime: Turbulent
Reynolds-Averaged Turbulence: K-Epsilon Turbulence



I am modeling 1.3 bars of helium going through a pipe-like environment. Please help me fix this, also does anyone have advice on what Reynolds-Average Turbulence model to use? Thanks in advance.
