Proper orthogonal decomposition (POD) combined with hierarchical tensor approximation (HTA) in the context of uncertain parameters
Steffen Kastian, Dieter Moser, Stefanie Reese +1
The evaluation of robustness and reliability of realistic structures in the presence of uncertainty involves costly numerical simulations with a very high number of evaluations. Th…
Asymptotic convergence of the parallel full approximation scheme in space and time for linear problems
Matthias Bolten, Dieter Moser, Robert Speck
For time-dependent partial differential equations, parallel-in-time integration using the "parallel full approximation scheme in space and time" (PFASST) is a promising way to acce…
A multigrid perspective on the parallel full approximation scheme in space and time
Matthias Bolten, Dieter Moser, Robert Speck
For the numerical solution of time-dependent partial differential equations, time-parallel methods have recently shown to provide a promising way to extend prevailing strong-scalin…
