原因在于你在求解p压力场，因此你不能给定calculatedFvPatchField边界条件。

In calculatedFvPatchField, those are all:

tmp<Field<Type> > calculatedFvPatchField<Type>::valueInternalCoeffs
(
    const tmp<scalarField>&
) const
{
    FatalErrorIn
    (
        "calculatedFvPatchField<Type>::"
        "valueInternalCoeffs(const tmp<scalarField>&) const"
    )   << "\n    "
...

when construct convection tern

fvm.internalCoeffs()[patchI] = patchFlux*psf.valueInternalCoeffs(pw);
fvm.boundaryCoeffs()[patchI] = -patchFlux*psf.valueBoundaryCoeffs(pw);

and laplacian term

fvm.internalCoeffs()[patchI] = patchGamma*psf.gradientInternalCoeffs();
fvm.boundaryCoeffs()[patchI] = -patchGamma*psf.gradientBoundaryCoeffs();

so...

上述问题您能再展开说一下嘛？我再求解rho1时遇到了相同的问题。
