Software Development

I mostly do programming in C++ and Julia, but also work with Python and Matlab.

The most important software libraries I work with:

• Baci: in-house multiphysics code (in collaboration with the Institute for Computational Mechanics (TUM))
• Trilinos: open-source project for algorithms for large-scale multiphsyics applications
• MueLu: next-generation multigrid framework within Trilinos

• DUNE: distributed and unified numerics environment
• preCICE: coupling library for partitioned multiphysics simulation
