Terra-Neo: Towards Earth Mantle Convection Simulation with Hierarchical Hybrid Multigrid Solvers

Principal Investigator: Ulrich Rüde , Lehrstuhl für Informatik 10 (Systemsimulation), Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)

HPC Platform used: JUWELS and JUQUEEN of JSC, Hazel Hen of HLRS

Local Project ID: cher16 (JSC), TN17 (HLRS)

Convection in the Earth’s mantle is the driving force behind large scale geologic activity such as plate tectonics and continental drift. As such it is related to phenomena like e.g. earthquakes, mountain building, and hot-spot volcanism. Laboratory experiments naturally fail to reproduce the pressures and temperatures in the mantle, thus simulation is a key ingredient in the research of mantle convection. However, since simulating convection in the Earth’s mantle is a very resource consuming HPC application as it requires extremely large grids and many time steps in order to allow models with realistic geological parameters, researchers turn towards GCS supercomputers to tackle this challenge.

Optical Simulations of Thin-Film Solar Cells

Principal Investigator: Christoph Pflaum , Department of Computer Science, University of Erlangen-Nürnberg (Germany)

HPC Platform used: SuperMUC of LRZ

Local Project ID: h0672

Organic Photovoltaics are a promising thin-film solar cell technology since all the constituting layers can be processed from solution processable materials. In order to improve the efficiency of those solar cells it is necessary to optimize their light trapping ability. Different techniques were evaluated in a research project on SuperMUC of LRZ.

TERRA-NEO: Integrated Co-Design of an Exa-Scale Earth Mantle Modeling Framework

Principal Investigator: Björn Gmeiner , Universität Erlangen-Nürnberg (FAU)

HPC Platform used: JUQUEEN of JSC

Local Project ID: her16

Mantle convection is a vital component of the Earth system. The relentless deformation taking place in the mantle by viscous creep has a far greater impact on our planet than might be immediately evident. Immense forces are at work in mantle convection cells: continuously reshaping Earth's surface, the mantle provides the enormous driving forces necessary to support large scale horizontal motion, in the form of plate tectonics and associated earthquake and mountain building activity.
