Problem with pipe in the box tutorial

Hello sirs,

I am a new user trying the tutorials and got stuck in the pipe in the box tutorial with this:
RANS Flow failed
Unexpected process exit.

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 : 327.059
Specified mass inflow : 0.306146
Specified mass outflow : 0
Adjustable mass outflow : 2.79676e-016

From function adjustPhi(surfaceScalarField& phi, const volVectorField& U,const volScalarField& p
in file cfdTools/general/adjustPhi/adjustPhi.C at line 116.

FOAM exiting


Any ideas?

Missing Outlet Boundary Condition

Check your boundary conditions. It sounds like you might be missing an Outlet condition.
