The OSPRE Scheme.

The following article is related to the OSPRE 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 OSPRE Scheme (Second Order Scheme).

The OSPRE scheme is based on the surface interpolation scheme and belongs to the limiter schemes such as the SFCD scheme. The flux limiter can be checked out in the OSPRE.H file and is based on the Limiter functions. As for any limiter scheme, the calculated limiter is bounded and modified accordingly to the scheme in use.
