Hi,
I'm using the pimplefoam solver to compute the unsteady flow in a 2d channel bifurcation with 1 inlet and 2 outlets and the simulation diverges because the mass flow is not balanced at the outlet. I didn't find any information on the parameter used in the pimple solver. Is it possible to make multiple sub-iteration as in the SIMPLE algorithm? Many thanks, Yannick |

Hi,
As I don't have any answer i will reformulate my question. Are these parameter OK to have PIMPLE behave like SIMPLE ? PIMPLE { nOuterCorrectors 5; nCorrectors 2; nNonOrthogonalCorrectors 0; pRefCell 0; pRefValue 0; } relaxationFactors { fields { } equations { "U.*" 0.7; "k.*" 1; "epsilon.*" 1; } } Many thanks, Yannick |

Yannick,
The fact that the mass flow is not balanced ( inlet 1 = outlet1 +outlet2), I think, points towards boundary conditions or any other issue rather than the pimple solver setup. Kalyan |
