A stencil-based implementation of Parareal in the C++ domain specific embedded language STELLA
Andrea Arteaga, Daniel Ruprecht, Rolf Krause
In view of the rapid rise of the number of cores in modern supercomputers, time-parallel methods that introduce concurrency along the temporal axis are becoming increasingly popula…
Probabilistic Schmid factors and scatter of LCF life
H. Gottschalk, S. Schmitz, T. Seibel +3
We investigate the scatter in the cycles to crack initiation for conventionally cast specimens of the superalloy RENE 80 in total strain controlled low cycle fatigue (LCF) tests at…
Parareal for diffusion problems with space- and time-dependent coefficients
Daniel Ruprecht, Robert Speck, Rolf Krause
For the time-parallel Parareal method, there exists both numerical and analytical proof that it converges very well for diffusive problems like the heat equation. Many applications…
Inexact spectral deferred corrections
Robert Speck, Daniel Ruprecht, Michael Minion +2
Spectral deferred correction (SDC) methods are an attractive approach to iteratively computing collocation solutions to an ODE by performing so-called sweeps with a low-order time…
