On Extrapolated Multirate Methods
2008) On Extrapolated Multirate Methods. Technical Report TR-08-12, Computer Science, Virginia Tech. (
In this manuscript we construct extrapolated multirate discretization methods that allow to efficiently solve problems that have components with different dynamics. This approach is suited for the time integration of multiscale ordinary and partial differential equations and provides highly accurate discretizations. We analyze the linear stability properties of the multirate explicit and linearly implicit extrapolated methods. Numerical results with multiscale ODEs illustrate the theoretical findings.
