In brief, the key features of BoSSS are:

• General framework to discretize general conservation laws by means of the DG method
• Highly modular object-oriented design based on C# (runs under .NET or mono and hence runs on Linux/UNIX and supercomputers/clusters)
• Generic in grid type (triangles, quads, cubes, tetras) and dimension (1D – 3D)
• Fully MPI parallel
• Parallel I/O: No parallel file system needed – load can be balanced to multiple fileservers
• Core routines for large linear systems have been written for GPUs
• Arbitrary repartitioning of grids (redistributes grid in any order; run on N processors – restart with M processors)
• Open source

• BoSSSpad worksheets enable a user to access all aspects of BoSSS without the burden of a full-featured programming environment. As a result, they can be used to create scripts for routine operations, without the need to define and maintain interface to a scripting language.
• Builtin-in cut-cell techniques allow for the usage of non-smooth and time-dependent basis functions within each computational cell (in the spirit of the eXtended Finite Element Method), while maintaining the full rate of convergence for smooths problems
