Detailed Description

This group contains OpenFOAM boundary condition types. All conditions are derived from the base Foam::fvPatchField class. Patch values are typically updated using the virtual functions.

• Foam::fvPatchField::updateCoeffs()
• Foam::fvPatchField::evaluate()

The difference between the methods is based on when the patch values are updated. When the condition is applied to a solution variable, the call to updateCoeffs() occurs as a preliminary step of the <matrix>.solve(). The evaluate() method is invoked after, or independent of the matrix solve, via a call to <field>.correctBoundaryConditions().
