Hi,
I am new to OpenFOAM and trying to run a laminar flow simulation using simplefoam with pressure inlet and flowrate outlet. However, I always get diverged results with large continuity errors. Any suggestions for this situation? The boundary condition files are attached below: U: dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { inlet { type outletInlet; outletValue uniform (0 0 0); value uniform (0 0 0); } outlet { type flowRateOutletVelocity; volumetricFlowRate 5.676455641980107e-07; value uniform (0 0 0); } walls { type noSlip; } } P: dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { inlet { type fixedValue; value uniform 12.3260377358; } outlet { type zeroGradient; } walls { type zeroGradient; } } Thanks in advance. Best, y |
