Hi,

it seems you're using fixedFluxPressure boundary condition. Look at the source code:

Code:
class fixedFluxPressureFvPatchScalarField
:
    public fixedGradientFvPatchScalarField
{
...
        //- Is the pressure adjoint, i.e. has the opposite sign
        Switch adjoint_;
...
so you just add 'adjoint no' to BC dictionary.

Change

}
to

Code:

can you give me information about P-RGH boundary condition?
for example the difference between buoyantpressure and fixedfluxPressre?

Well, I can't. Go to $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived and read the code of each BC you're interested in.
