Now that thermal transport is implemented as an energy implicit correction on an explicit temperature gradient formulation it is more efficient if the implicit correction contains only the implicit terms of the matrix and not the explicit non-orthogonal or anisotropic correction terms which are cancelled anyway when the evaluation of the matrix for the current state is subtracted. The new fvm::laplacianCorrection functions provide a convenient mechanism to efficiently evaluate only the implicit correction to the laplacian and is now used in all the thermophysicalTransportModels.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
