在实际计算过程中可以将其中的一个设置为 0,则达到另外一个残差,则停止迭代,当然不能两个都设置为 0(因为残差为 0 永远达不到)。在 OpenFOAM 求解器中压力方程常见有 p(或者 p_rgh)及其pFinal(p_rghFinal),p(或者 p_rgh)用来求解压力修正方程的中间步骤,而 pFinal(p_rghFinal)为最后一次修正过程的代数方...
2、p_rgh文件 p_rgh文件内容如下所示。 FoamFile{ version 2.0; format ascii; class volScalarField; location "0"; object p_rgh;}// * * * * * * * * * * * * * * * * * //dimensions [1 -1 -2 0 0 0 0];internalField uniform 0; boundaryField{ TOP { type symmetry; } BOTTOM...

Info<< "Reading field p_rgh\n" << endl; volScalarField p_rgh //相对压力场 ( IOobject ( "p_rgh", runTime.timeName(), mesh, IOobject::MUST_READ, IOobject::AUTO_WRITE ), mesh ); Info<< "Reading field U\n" << endl;
然后我们再来看一下p_rgh这个文件: dimensions [1 -1 -2 0 0 0 0]; //量纲为M/(L*T2) internalField uniform 0; boundaryField { leftWall { typefixedFluxPressure;// 它表示边界处压力通量为固定值。它自动调整压力梯度使边界通量符合速度边界条件。
to convert from p to p_rgh If the hydrostaticMode is active, values are also required for gravity, g, and reference height, hRef. By default these will be retrieved from the database. When these values are not available the user must provide them, e.g. g (0 -9.81 0); hRef 0;...
