The QuadraticFit Scheme.

The following article is related to the QuadraticFit class, implemented in OpenFOAM®. This article describes the implementation and usage of the numerical scheme. If the code explanation is missing Holzmann CFD does not get enough support from the community to investigate into the code segments.

General Remarks.

The QuadraticFit Scheme (Second Order Scheme).

The QuadraticFit scheme is based on the surface interpolation scheme. The calculation is based on a quadratic fit algorithm.
