Announcements

  • The kickoff session to introduce seminar topics and organizational details will be held on Wed, Oct 21, 16.00 at the chair of Prof. Igel (LMU, Theresienstr. 41, seminar room C406 "Lamont")
  • An introductory session to present details on the seminar and with the opportunity to pre-register (cf. matching system) will be held on Tue, Jul 7, 15.00 in room MI 02.07.023

Description

Numerical simulation offers insight into many processes in the geosciences. Simulation of seismic wave propagation, for example, helps to shed light on the Earth's interior structure. Together with the simulation of dynamic rupture processes of earthquakes, such simulations help to better understand earthquakes and estimate respective hazards. Similar simulation challenges exist in geodynamics, ocean flows, etc.

In this seminar we will select important aspects from the entire simulation pipeline. We will cover questions of physical modelling as well as availability and usage of geo-data. We will discuss numerical approaches used to solve the respective models. In addition, we will illustrate some of the computational challenges to solve: from generating discretization meshes and input/output of data up to the efficient implementation of large-scale problems on supercomputers.

A strong focus of the seminar shall be on application and implementation of the concepts discussed: all participants will be encouraged to demonstrate their presented methods and concepts via small projects, which requires extensive use of the learned theory.

Organization

The seminar will be organzed together with the Department of Earth and Environmental Sciences of the Ludwig-Maximilians-University.
