Modelling and Simulation


Organisation:
Lehrstuhl für Werkstoffwissenschaften (Werkstoffkunde und Technologie der Metalle)

FAU Contact:
Markl, Matthias Dr.-Ing.

Description:
The group Modelling and Simulation develops and implements new software:

  • Process simulation of beam-based additive manufacturing in powder beds
  • Multi-criteria optimization for alloy development
  • Process simulation of foam formation

The aim is to explain process dependent phenomena and to predict new process strategies / alloys. Therefore, the underlying effects are physically modelled, numerically implemented and experimentally validated. Different numerical approaches are applied, like the lattice Boltzmann method, finite difference methods, cellular automata and probabilistic and deterministic search algorithms.
