Hi,

I am trying to use the simpleBouyantFoam solver with inlets and outlets.

The problem is that it is complaining over a continuity error in the outflow.

--> FOAM FATAL ERROR : Continuity error cannot be removed by adjusting the outflow.

Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.

Total flux : 76.8043
Specified mass inflow : 10.4276
Specified mass outflow : 0
Adjustable mass outflow : 1.17153e-16


From function adjustPhi(surfaceScalarField& phi, const volVectorField& U,const volScalarField& p
in file cfdTools/general/adjustPhi/adjustPhi.C at line 111.

FOAM exiting

So I tried to look at my boundaryconditions. They seem fine. Then I looked at potentialFoam. My problem is that if I want to initialise the outflow. p is calculated as p/rho. That is: the dimensions for p are not the same in potentialFoam as they are in bouyantSimpleFoam.

If someone has any ideas how to solve/omit this problem I would be very happy.

Best Regards,
Lasse
