Abstract

Flow problems with moving boundaries and interfaces appear naturally in many applications, such as turbine flow, flapping flight, etc. Numerical modeling of these flows poses additional challenges since the numerical grid moves with time. The arbitrary Lagrangian-Eulerian method (ALE) is one of the solution strategies for numerically dealing with moving boundary problems. In this talk, we present an arbitrary Lagrangian-Eulerian method on GPUs for moving boundary problems and its implementation to an open-source discontinuous Galerkin library, libParanumal.
