An EigenValue Stabilization Technique for Immersed Boundary Finite Element Methods in Explicit Dynamics
Sascha Eisenträger, Lars Radtke, Wadhah Garhuom +4
The application of immersed boundary methods in static analyses is often impeded by poorly cut elements (small cut elements problem), leading to ill-conditioned linear systems of e…
Spectral deferred correction methods for second-order problems
Ikrom Akramov, Sebastian Götschel, Michael Minion +2
Spectral deferred corrections (SDC) are a class of iterative methods for the numerical solution of ordinary differential equations. SDC can be interpreted as a Picard iteration to…
Vibroacoustic simulations of acoustic damping materials using a fictitious domain approach
Lars Radtke, Paul Marter, Fabian Duvigneau +3
The numerical investigation of acoustic damping materials, such as foams, constitutes a valuable enhancement to experimental testing. Typically, such materials are modeled in a hom…
Temporal approximation of stochastic evolution equations with irregular nonlinearities
Katharina Klioba, Mark Veraar
In this paper, we prove convergence for contractive time discretisation schemes for semi-linear stochastic evolution equations with irregular Lipschitz nonlinearities, initial valu…
Parareal with a physics-informed neural network as coarse propagator
Abdul Qadir Ibrahim, Sebastian Götschel, Daniel Ruprecht
Parallel-in-time algorithms provide an additional layer of concurrency for the numerical integration of models based on time-dependent differential equations. Methods like Parareal…
Pathwise Uniform Convergence of Time Discretisation Schemes for SPDEs
Katharina Klioba, Mark Veraar
In this paper, we prove convergence rates for time discretisation schemes for semi-linear stochastic evolution equations with additive or multiplicative Gaussian noise, where the l…
