About me
My path to simulation science in general and CATS in particular started with a diploma in Mechanical Engineering, majoring in "Manufacturing Techniques for Microsystems". In 2011, I completed my PhD thesis with the topic "Free-Surface Flows in Shape Optimization of Extrusion Dies". This was followed in the year 2016 by my habilitation on "CAD-Conforming Finite Element Methods in Engineering Design". In October 2019, I took over the professorship for leightweight design at TU Vienna.
From 2012-2015, I was a member of the GAMM-Juniors, acting as vice-spokesperson from 2013-2014. Currently, I am co-chairperson of the ECCOMAS Young Investigator Group.
Research
My current research interests lie in the simulation and numerical design of primary manufacturing processes. From the mathematical point of view, this constitues an inverse problem. Together with my work group, I have considered applications in the area of plastics profile extrusion, injection molding, as well as high-pressure die casting. Our task is the simulation of all process steps ranging from the filling via solidification to the computation of warpage and residual stresses. These simulations serve as a basis for shape optimization of the cavity and the cooling channels.
The methods we employ for these applications encompass:
- free-surface flow,
- mesh-deformation methods,
- non-Newtonian material models,
- spline-based finite element methods,
- PDE-constrained shape optimization techniques.
