Modelling Fragmentation in Large Scale DEM Simulations

PhD Position: Modelling Fragmentation in Large-Scale DEM Simulations

Location: Friedrich-Alexander-Universität Erlangen, Germany; Institute for Multiscale Simulation
Duration: 36 months
Start: as soon as possible

Project overview: Discrete Element Simulation (DEM) is an important method for the numerical simulation of the statics and dynamics of granular materials. DEM has been generalised to describe grinding and comminution processes in such a way that the breakage of particles can now also be taken into account. However, the treatment of particle breakage is currently not yet satisfactory, both in terms of the physical correctness of the fracture mechanics and the numerical efficiency of the algorithms.
The aim of the current research project is to develop a physically accurate and efficient numerical method for describing particle breakage in DEM simulations, building upon existing preliminary work, and to implement it on a high-performance computer. This method should enable large-scale DEM simulations of comminution, wear, and grinding processes to be carried out.

Profile of the ideal applicant:

We look for a PhD student with the following qualifications:

  • Master’s degree in physics, mechanical engineering, materials science, computational engineering, computer science (with a strong interest in physics), or related subjects
  • Excellent programming skills, preferably in C++ and Python
  • Ideally (but not necessary) experience in one or more of the following areas: high-performance computing, efficient algorithms, particle simulations, data analysis, and visualization
  • Strong academic writing skills and clear communication skills in English
  • Ideally (but not mandatory) knowledge of the German language

Scientific environment: The position is embedded in the graduate programme ‘Fracture across Scales’ (FRASCAL), and the workplace is the Institute for Multiscale Simulation (MSS). The PhD student will develop the physical model and the algorithm to simulate the fragmentation of DEM particles. The simulation method will be developed in close cooperation with the other PhD students, postdoctoral fellows, and professors of FRASCAL and the MSS.

This position offers an exceptional multidisciplinary environment with close collaboration between simulation and experiment, access to high-performance computing resources, and interactions with researchers at MSS, FRASCAL, and across the Friedrich Alexander University.

Salary and conditions: The position is paid according to the German income scheme for public service, level TVL E13. This salary is standard for postdocs, but we only accept outstanding PhD students. The position is for 3 years.
