Partially Implicit BDF2 Blends for Convection Dominated Flows
In this paper we consider various blends of implicit and explicit time integration schemes, based on the well-known BDF2 method, applied to convection-diffusion problems with dominating convection. A fully implicit treatment of convection terms is often not very efficient. We shall deal with second order schemes that are implicit in …
