access field value at boundary face and nearest cell in boundary condition class

mehtab · October 21, 2015, 19:02

Hi,

I want to know how can I access a field value eg Temperature at a patch (boundary face) and how can I do the same for nearest boundary cell.

Code:

const fvMesh& mesh = patch().boundaryMesh().mesh();
const volScalarField& T= mesh.lookupObject<volScalarField>("T");

The above code is accessing value at boundary face or nearest cell? And What should be the code for other case?

Thanks
Maqs

This post should help accessing patch face values directly:
