Where do the BC are used/read in OpenFOAM?
 

Hello everybody,

if I for example define a BC as zeroGradient, in which "file" or method does OpenFOAM create the values for the boundarycells?
Especially I am looking for this in dsmcFoam, but I think, that there should be no bigger difference to other solvers.

What I still have is this:

boundaryT_
(
volScalarField
(
IOobject
(
"boundaryT",
mesh_.time().timeName(),
mesh_,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh_
)
),


I think, that this has something to do with it, but the IOObject.C didnt help me at all...
