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, ADER-Approach
  • Stability Properties 
  • Approximation Theory 
  • Uncertainty Quantification in CFD 
  • Edge Detection and Shock Sensors

    News:


    • Today (28.7.2021), I will speak about "Convergence of Discontinuous Galerkin Schemes for the Euler Equations via Dissipative Weak Solutions" at the NumHyp 2021. 
    • This week (12.7-16.7.2021), I will participate at ICOSAHOM2020 in Wien. I will give two talks. The first talk is on Monday about Relaxation DeC and the second one is on Thursday on RD and structure preserving methods. 
    • My new preprint "Relaxation Deferred Correction Methods and their Applications to Residual Distribution Schemes" with Remi Abgrall, Elise Le Meledo and Davide Torlo is on ArXiv. 
    • 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.
