Between 2017 and 2021 I actively contributed to Kratos Multiphysics, an open source framework for modeling and simulation of problems with coupled physics in an HPC context. Among other things, I added strategies for modal analysis of problems from structural dynamics and contributed an interface to FEAST v4.0 to solve the required eigenvalue problems. An extension for Kratos to model vibro-acoustic problems including finite element formulations for acoustic fluids, poroelastic materials, and their coupling and strategies for frequency domain analysis of dynamical systems is available on my personal fork.
During my time as a research assistant at TUM, I was actively involved in the development of a finite element code to be used in teaching. The object-oriented code features analysis in time and frequency domain and includes finite element formulations for various types of problems, e.g. structural shells, acoustic fluid, or poroelastic materials. The code is intended to show students the main steps of finite element analysis and was developed with modular expandability in mind.
