mean_mass_fraction with lagrangian model

[Maxime Nibart]

Hello,

i am running Code_saturne CS2_RC2 on a atmospheric case with a frozen wind field and dispersion with the lagrangian model.

Both lagrangian and atmopheric modules seems not fully compatibles : the particles always go up. There is may be a problem with the hydrostatic pressure.

Anyway my validation case is a windtunnel case, so I have run a calculation without the atmospheric module. It seems to work fine. My very first results are not too bad.

But , to compare the calculated/measured concentrations, I have used the output field named "mean_mass_fraction" and actually I think this is a volume_fraction.

Could you confirm this?

Maxime,
Of course, you're right. It's a mistake in the GUI, we will correct that.
