Talk ‘Robust and efficient time integration methods for compressible fluid dynamics’ at the collaborative research center TRR 146: Multiscale Simulation Methods for Soft Matter Systems

I will give a talk Robust and efficient time integration methods for compressible fluid dynamics at the collaborative research center TRR 146: Multiscale Simulation Methods for Soft Matter Systems on Thursday, January 16, 2025, 14:30 - 16:00 in room 05-119, Staudingerweg 7 (Minkowski-Raum) in Mainz.

Abstract:

Compressible computational fluid dynamics (CFD) is an active and fruitful area of research. In this talk, we will focus on time integration methods optimized for CFD applications. We will briefly review the classical Courant-Friedrichs-Lewy (CFL) constraint and present error-based time step size control as an alternative. In particular, we will discuss how the design of the methods influences their efficiency and robustness. Combining theoretical analysis with a data-driven approach, we will present new optimized time integration methods for compressible CFD applications that are available in open-source software.

The talk will be hybrid, see https://trr146.uni-mainz.de/seminars/.
