Hi Foamers,


I would like to use the flowRateOutletVelocity boundary condition with a compressible fluid (I am using compressibleInterFoam).


I want to impose a mass flow rate, so I am using the following specifications:

        

        type                flowRateOutletVelocity;
        massFlowRate        0.03;
        rho                 rho;

With this settings, I am getting the following error


--> FOAM FATAL ERROR:
Did not find registered density field rho and no constant density 'rhoOutlet' specified


which is strange as the volScalarField rho is speficied in my time folder.


I don't want to use a constant density to estimate the mass flow rate (as with rhoOutlet option), but I want to use the density field rho computed by the solver.
Is it even possible ?


Thanks for your help,
Mat
