Report on the development of a generic discontinuous Galerkin framework in .NET

In the past 1.5 years, the authors have been working on an object-oriented framework for the discontinuous Galerkin (spectral element) method, with a strong aim on CFD applications. This library was programmed in C# for Microsoft .NET and Mono framework. Up to our knowledge, it's the first ambitious CFD code which was implemented using the .NET framework. This paper covers various topics: A brief overview of features, library layout and current implementation status. Advantages of managed programming languages (in comparison to classical languages) and possible performance pitfalls in managed platforms are discussed. Benchmarks supporting these arguments are given and discussed. Finally, a mathematical framework for parallel IO is presented
