Dr. Bosco García-Arcilla, Universidad de Sevilla: "On the order of error estimates for finite-element methods applied to time-dependent convection-dominated problems"

23.09.2019 von 16:00 bis 17:00

LMS 4 - Raum 325 - Seminarhörsaal

Abstract:

We review the error estimates of finite-element methods for time dependent (linear) convection-diffusion problems and the Navier-Stokes equations. We analyze the order reduction in error estimates when convection dominates (or, equivalently, large Péclet number and large Reynolds number), the sources of this phenomenon and the remedies provided by stabilized methods.
