Hello,

In a model of a nozzle i've to set up the density of my gas to constant in the first iteration...
It's the first time, i have to do this, before, i set up 0.4 for the pressure urf and 0.3 for momentum and finally i turned off the energy but with real gas model!!!!

Could you explain me, why sometimes this problem appears.

Thanks

I forgot:

After few iteration with constant density, the model converge even when i change for ideal gas.

Thanks
