Job offer from January 16, 2020
The method of Dynamic Mode Decomposition (DMD) is able to identify a surrogate model for a nonlinear system based on time series (snapshots). Typically, surrogate models are less complex than the original model equations so that they can be used to simulate the same phenomena but in less computation time (speedup) and with lower memory requirements (compression). The theory of DMD is more than 100 years old. In practice, DMD has experienced strong popularity within the last 10 years, mostly due to interesting and successful application examples in flow problems.
In the context of numerical investigation of PDEs in general and flow problems in particular, the snapshots can be considered as approximate solutions at given time instances. Each of these approximate solutions are discrete functions which are defined on a spatial mesh. If the mesh is constant over all time instances, DMD is readily applicable.
In this master's thesis, we will pursue the case, in which the mesh changes over time, which is intended in applications. We will develop a formulation for DMD which is independent of the spatial meshes and propose numerical realizations which exceed simple interpolation approaches.
For this work, knowledge or particular interests in the following fields are of advantage:
- numerics of partial differential equations and
- numerical simulation,
- as well as programming expertise (most suitable in Python or C++).
- working in a scientific research institute
- investigating a recent and relevant topic
- participation in research seminars
- first-class supervision
Please send your application in German or English to the contact and include a short CV and transcript of records. Deadline of application is April 30, 2020.
The Max Planck Society is committed to increasing the number of individuals with disabilities in its workforce and therefore encourages applications from such qualified individuals. Furthermore, the Max Planck Society seeks to increase the number of women in those areas where they are underrepresented and therefore explicitly encourages women to apply.
