Default Density condition in Fluent

Posts: n/a

I am doing a simulation on an inlet geometry of an engine. Ideally in the materials panel i want to set the Ideal Gas condition along with either segregated or coupled solver.

The solution is getting diverged with Ideal gas condition,but it does converge with constant Density setting.

Is there any specific reason why the solution is diverging with Ideal Gas setting.Also at the higher velocities the segregated solution is getting diverged.
