The QUICK Scheme

The following article is related to the QUICK 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. Just imagine, if you would do such a voluntary work. Would you do it? 

General Remarks

The QUICK Scheme (Second Order Scheme)

The QUICK scheme is based on the surface interpolation scheme and belongs to the limiter schemes such as the SFCD scheme. The flux limiter is sign depended and thus, the scheme takes the flux direction into account. The scheme is used specially for steady-state flows with elliptic character.The scheme produces non-physical results in the following case but is stable in case of error accumulation. In the documentation it is mentioned that the weighting factors are not bounded between the upwind and central differentiating based on the fact that some downwind contribution can be possible.
