Towards a Unified Framework for Finite Element Computations
Abstract: Finite Element implementations range from small and simple model problem applications to large frameworks incorporating many different finite element variants, state-of-the-art solvers, adaptive mesh refinement and parallel computation capability. The large frameworks typically have evolved over many years, are difficult to use and may be inefficient for particular applications with respect to memory and run-time. In this talk we present an object oriented approach to finite elements that is intended as an open, public domain software platform. Its particular features are:(1) Flexibility (higher order methods, systems of PDEs, adaptivity), (2) Reusability of old code (E.g. Albert, UG) and (3) Efficiency on single and multiprocessor machines.
These features are achieved through the consequent use of static polymorphism.
The talk discusses the design of the code with emphasis on the grid abstraction. Already existing applications include a large scale explicit finite volume scheme and a parallel algebraic multigrid solver.
