This boundary condition

你不需要指定其他信息，这样即可：

type calculated;

[mark]

FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [1 -1 -2 0 0 0 0];

internalField uniform 3e+06;

boundaryField
{
INLET
{
type calculated;
}

WALL
{
    type            zeroGradient;
}

OUTLET
{
    type            calculated;
}

}

这样设置好像不行啊@cfd-china

这不是因为边界条件导致的哦。估计是除以0了:sunglasses:
