Default inletOutlet BC & interpolation

Hi Foamers,

a short question:

given a volScalarField a with BC's:
type inletOutlet;
inletValue uniform 1130;
value uniform 0;
type zeroGradient;
if interpolated on cell faces
surfaceScalarField af (fvc::interpolate(a));
the boundaries look like
type calculated;
value uniform 0;
type calculated;
value uniform 500;
The right one is interpolated properly, but the left one is zero, even though neither the cell values nor the inlet value are zeros.

Can anyone please tell me why?

Hi Illya,

Is there a non-zero internal value for your field? I'm just trying to get a little more information, this seems a little strange indeed.

Now that you bring it up, I'm not %100 sure how the interpolation operator works with boundary values of a vol field...
