## gaussLaplacianScheme(1/3): Theory and implementation in OpenFOAM

How the discretisation of the laplacian term is done? explicit evaluations, orthogonal corrections … Notes made while reading through report by Jesper Roland. This report has detailed explanation on laplacianScheme abstract class, various macros like TypeName, New,… etc. Options for laplacian scheme A typical system/fvSchemes will read like below: Gauss is the only laplacian scheme …
