旋流器以水为介质在SimpleFoam中层流计算时,速度入口正常,两个压力出口全为负值,困惑
以下是我的p, u, fvSolution
object p; dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { inlet { type zeroGradient; } outlet { type fixedValue; value uniform 0.002; } outlet_sec { type fixedValue; value uniform 0.0015; } wall { type zeroGradient; } } object U; dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { inlet { type fixedValue; value uniform (-3.2 0 0); } outlet { type zeroGradient; } outlet_sec { type zeroGradient; } wall { type noSlip; } } object fvSolution; solvers { p { solver GAMG; tolerance 1e-06; relTol 0.1; smoother GaussSeidel; } "(U|k|epsilon|omega|f|v2)" { solver smoothSolver; smoother symGaussSeidel; tolerance 1e-05; relTol 0.1; } } SIMPLE { nNonOrthogonalCorrectors 0; consistent yes; residualControl { p 1e-2; U 1e-3; "(k|epsilon|omega|f|v2)" 1e-3; } pRefCell 0; pRefValue 0; } relaxationFactors { equations { U 0.9; ".*" 0.9; } }
