Beschreibung

The research group Numerical Mathematics and Scientific Computing of
student in the area of Scientific Computing/HPC. The research of the group
is focused on the analysis and scalable implementation of robust domain
decomposition methods, efficient solution methods for discretized partial dif
- ferential equations, scientific machine learning, and scalable homogenization

YOUR TASKS

Work in the research unit FOR5134 "Solidification cracks in laser beam

welding - High performance computing for high performance
Research Foundation (DFG). A focus of the project is to develop a
process understanding on the formation of solidification cracks and
their correlation to process parameters during laser beam welding.
High-performance simulations and experiments as well as the effect
on three different scales are considered in the different sub-project. In
the research unit, Bundesanstalt für Materialforschung und -prüfung,
University of Erlangen-Nuremberg, University of Duisburg-Essen, and
university of applied science in Karlsruhe are involved as further partners.

Work on the subproject "Efficient, robust, and highly scalable implicit

solvers for the simulation of thermoplastic solidification processes"

Extension of the highly scalable computational homogenization software

FE2TI (based on FE^2 method) to carry out micro-macro simulations
of the thermo-elasto-plastic processes at the solidification front

Implementation of timedependent representative volume elements in

FE2TI based on the dendritic growth on the microscale during solidification

Development and implementation of scalable

nonoverlapping domain decomposition solvers for
thermo-elastic and thermo-elasto-plastic problems

YOUR PROFILE

Excellent university degree (master or diploma) in mathematics,

computational science & engineering or comparable studies

Good skills in the area of parallel implementation
Solid command of C/C++ as well as MPI
Good knowledge in the area of discretization of partial

differential equations, ideally with finite elements

Experience in the area of homogenization appro

- aches, ideally with the FE^2 method

Solid command of German and English, both written and spoken
Good communication and teamwork skills
