The LimitedCubic Scheme.

The following article is related to the limitedCubicLimiter class, implemented in OpenFOAM®. This article describes the implementation and usage of the numerical scheme. If the code explanation is missing, it is related that Holzmann CFD does not get enough support from the community and all people around the world.

General Remarks.

The LimitedCubic Scheme (Second Order Scheme).

The limitedCubic scheme is based on the surface interpolation schemes and calculates a limiter using a cubic interpolation formulation. After the limiter is calculated, the limiter value itself is limited to obey the TVD constrains.
