Selected research, projects, ...
The following is an extremely incomplete list of my activities. I just started collecting them and they should grow over time ...
- I recently started looking into discontinuous Galerkin (DG) and Finite Volume (FV) methods for hyperbolic equations, such as approximating the solution \(u\) of: $$\partial_t u + \nabla_x \cdot f(u) = 0$$ I was particularly interested in how to support the implementation of both FV and DG methods in our software library.
Preliminary findings aredocumented here.This is now part of our library dune-gdt (FV is joint work with T. Leiber), see for instance the advection operators here or these tests on linear transport and inviscid compressible flow.

Software
dune-gdt
Joint work with: Rene Milk, Tobias Leibner
dune-gdt is a DUNE module which provides a generic discretization toolbox for grid-based numerical methods. It contains building blocks - like local operators, local integrands, local assemblers - for discretization methods and suitable discrete function spaces. For more information visit the official homepage.

Joint work with: Stephan Rave, Rene Milk
pyMOR - Model Order Reduction with Python - is a software library for building model order reduction applications with the Python programming language. Its main focus lies on the application of reduced basis methods to parameterized partial differential equations. All algorithms in pyMOR are formulated in terms of abstract interfaces for seamless integration with external high-dimensional PDE solvers. Moreover, pure Python implementations of finite element and finite volume discretizations using the NumPy/SciPy scientific computing stack are provided for getting started quickly. For more information visit the official homepage.
