In the field of scientific computing there is a manifold of software applications and tools available which provide methods and libraries for the solution of very specific problem classes [1, 13,15, 22,26]. They are mostly specialized on a certain type of underlying mathematical model resulting in a solution process which is highly predictable. We have designed a topological library [11] which enables the development of an equation specification mechanism for all different kinds of discretized partial differential equation by utilizing functional programming. This work examines the performance aspects of our domain specific embedded language (DSEL) approach for mathematical equation specification.
