Max Firmbach M.Sc.

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:

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

Academic Career

04/2021 -  Doctoral Researcher, Institute for Mathematics and Computer-Based Simulation, University of the Bundeswehr Munich
10/2018 - 03/2021 Master of Science, Computational Science and Engineering, TU Munich
09/2014 - 05/2018 Bachelor of Engineering, Aerospace Engineering, University of Applied Sciences Aachen

Research Interests

  • Multiphysics Simulation: partitioned and monolithic coupling approaches for fluid-structure interaction, thermo-mechanical simulation and more interesting scenarios


Fluid-Structure Interaction of a lid-driven cavity with flexible bottom simulated with a partitioned coupling using DUNE, preCICE and OpenFOAM


Deformation of a flexible pipe due to a traveling pressure wave simulated by a partitioned coupling using DUNE, preCICE and OpenFOAM
