Hi everyone,
I am running this case to understand how interFoam manages gravity. It consists of a horizontal pipe with Newtonian laminar flow, with a vertical gravitational field. The pipe length is chosen so that the flow is fully developed at the outlet. You can see from the attached image that the flow at the outlet seems not to be affected by the gravity, as it depicts a typical pipe flow profile without gravity. I cannot explain the this behaviour. Perhaps did I make something wrong at the boundary conditions? 0/p_rgh Code:
dimensions [1 -1 -2 0 0 0 0]; internalField 1e5; boundaryField { inlet { type fixedFluxPressure; } outlet { type totalPressure; p0 uniform 0; phi phi; U U; rho rho; psi none; gamma 0; value uniform $internalField; } fixedWalls { type fixedFluxPressure; } } Code:
dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { inlet { type fixedValue; value uniform (0 0 0.5); } outlet { type zeroGradient; } fixedWalls { type fixedValue; value uniform (0 0 0); } } |

The solution is correct.
Regards.
