Philipp Öffner
Dr. rer. nat.
Hi, my name is Philipp Öffner. Currently, I am substituting a professorship in numerical analysis at the Johannes Gutenberg-University Mainz.
Prior to JGU, I was a postdoctoral researcher at the University Zurich and at the Technical University of Brunswick.
In my research, I focus on the analysis and development of numerical methods for partial differential equations, especially for hyperbolic conservation/balance laws.
In particular, I am interested in stability properties, the preservation of physical constraints and convergence properties.
Research Interests
- Computational Fluid Dynamics (CFD)
- Numerical Methods for Compressible and Incompressible Flows: Continuous and Discontinuous Galerkin, Flux Reconstruction, Residual Distribution Schemes
- Time Integration Schemes: Deferred Correction Methods, Runge-Kutta Schemes
- Stability Properties
- Approximation Theory
- Uncertainty Quantification in CFD
- Edge Detection and Shock Sensors
News:
- Yesterday (18.05.2021), I have passed my trial lecture for the habiliation in Zurich. The topic was "Imex Methods and their Application". Since my thesis was already accepted in January, this was the last step to get the habiliation.
- From 1.4.2021, I substitute the professorship in Mainz.
- Today, I am presenting in the Oberwohlfach workshop: "Hyperbolic Balance Laws: modeling, analysis, and numerics" (2.3.20221). The topic of the talk will be "Extension of Entropy Correction Terms for Residual Distribution Schemes: Application to Structure Preserving Discretization".
- My paper " Towards Stable Radial Basis Function Methods for Linear Advection Problems" with Elise Le Meledo and Jan Glaubitz has been accepted in
Computers and Mathematics with Applications (18.1.2021).
- My paper "DeC and ADER: Similarities, Differences, and a Unified Framework" with Maria Han Veiga and Davide Torlo has been accepted in Springer Journal of Scientific computing (13.12.2020).
