Invited Lecture
New developments in multirate integration
Virginia Tech, Blacksburg, VA, USA
Abstract
Multirate methods seek to solve efficiently dynamical systems
characterized by multiple time scales. The solution strategy is to use small step sizes to discretize the fast
components, and large step sizes to discretize the slow components.
This talk will discuss the new family of multirate infinitesimal
GARK schemes, where the fast component is advanced by solving an appropriate
ODE, thereby allowing extreme flexibility in practical implementations.
The talk will also discuss new multirate General Linear Methods.
