simpleFoam质量流出口出现奇点
-
大家好,我在使用 simpleFoam 计算外流场时,利用质量流出口作为驱动,计算结果在出口处出现了奇点,以下为最新设置的 U 和 P,供各位参考,奇点的出现原因是什么?是否和边界类型有关?希望能收到大家的回复。
U文件如下
FoamFile { version 2.0; format ascii; class volVectorField; location 0; object U; } dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { outFlow_car { type noSlip; } outFlow_inlet { type pressureInletUniformVelocity; value $internalField; } outFlow_wall { type noSlip; } outFlow_bottom { type noSlip; } outFlow_outlet { type flowRateInletVelocity; massFlowRate constant -10; rho rho; rhoInlet 1; } }
P 文件如下
FoamFile { version 2.0; format ascii; class volScalarField; location 0; object p; } dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { outFlow_car { type zeroGradient; } outFlow_inlet { type fixedValue; value $internalField; } outFlow_wall { type zeroGradient; } outFlow_bottom { type zeroGradient; } outFlow_outlet { type zeroGradient; } }
谢谢!
