The aim of this project is the development of special problem-adapted simulation tools, which are suitable as plugin extensions for standard simulation packages.

Today's simulation applications are characterized by ever increasing problem sizes and the use of increasingly complex models.  As a result, the demands on the efficiency and scalability of the simulation environment are becoming more and more important.  In particular, many applications require the use of domain-specific or problem-adapted simulation tools and correspondingly adapted mathematical methods to solve the resulting large systems of equations.  An example for this is the oil interface of SAMG developed by SCAI, which takes care of out the highly specialized pre-processing of the linear equation systems, that result from the discretization of the complex models of the oil reservoir simulation, in order to successfully apply SAMG to the entire coupled system.

In practice, open source simulation packages are increasingly being used.  The aim of the project is therefore to develop specialized extensions of such open source simulation packages in combination with a corresponding solver interface for SAMG.  For this purpose, a series of OpenFOAM extensions will be developed, which are only possible in special application areas by combining solver and discretizer expertise.  Another open source package that we want to extend in a similar way is CSC/Elmer.
