Convergence of Parareal for the Navier-Stokes equations depending on the Reynolds number
Johannes Steiner, Daniel Ruprecht, Robert Speck +1
The paper presents first a linear stability analysis for the time-parallel Parareal method, using an IMEX Euler as coarse and a Runge-Kutta-3 method as fine propagator, confirming…
Probabilistic Analysis of LCF Crack Initiation Life of a Turbine Blade under Thermomechanical Loading
Sebastian Schmitz, Georg Rollmann, Hanno Gottschalk +1
An accurate assessment for fatigue damage as a function of activation and deactivation cycles is vital for the design of many engineering parts. In this paper we extend the probabi…
A Probabilistic Model for LCF
Sebastian Schmitz, Thomas Seibel, Tilman Beck +3
Fatigue life of components or test specimens often exhibit a significant scatter. Furthermore, size effects have a non-negligible influence on fatigue life of parts with different…
A space-time parallel solver for the three-dimensional heat equation
Robert Speck, Daniel Ruprecht, Matthew Emmett +2
The paper presents a combination of the time-parallel "parallel full approximation scheme in space and time" (PFASST) with a parallel multigrid method (PMG) in space, resulting in…
A multi-level spectral deferred correction method
Robert Speck, Daniel Ruprecht, Matthew Emmett +3
The spectral deferred correction (SDC) method is an iterative scheme for computing a higher-order collocation solution to an ODE by performing a series of correction sweeps using a…
Risk estimation for LCF crack initiation
Sebastian Schmitz, Georg Rollmann, Hanno Gottschalk +1
An accurate risk assessment for fatigue damage is of vital importance for the design and service of today's turbomachinery components. We present an approach for quantifying the pr…
