Hi! How do I fix this warning? I already selected Ideal-Gas from the Density drop down list and this error keeps on showing in my console....

Warning: Pressure far-field boundary condition can only be used with ideal gas law.

Please change either the boundary condition type or enable ideal gas law.

Solver cannot proceed until this is fixed.

Note: Enabling energy equation as required by material density method.

Go to materials and select ideal gas law for density.
If that persist, please change boundary condition to pressure outlet.

If you're using a species mixture you need to change the material property in the mixture, not the fluid.

Hi! I tried all your instructions and it worked. However, This "Note: Enabling energy equation as required by material density method." keeps on showing in my console. is there anything I do to fix this?

It's a warning. If you want ideal gas the solver will turn on the energy equation. To avoid the warning turn the energy equation on before setting ideal gas. Same overall outcome but you won't see the warning.

Thank you sir for answering all of my questions. I don't have anyone to ask about this software that's why I have a lot of questions. Hope I can return the favor someday.
