Time-periodic steady-state solution of fluid-structure interaction and cardiac flow problems through multigrid-reduction-in-time

Andreas Hessenthaler, Robert D. Falgout, Jacob B. Schroder +3

In this paper, a time-periodic MGRIT algorithm is proposed as a means to reduce the time-to-solution of numerical algorithms by exploiting the time periodicity inherent to many app…

Tight two-level convergence of Linear Parareal and MGRIT: Extensions and implications in practice

Ben S. Southworth, Wayne Mitchell, Andreas Hessenthaler +1

Two of the most popular parallel-in-time methods are Parareal and multigrid-reduction-in-time (MGRIT). Recently, a general convergence theory was developed in Southworth (2019) for…

A Class of Analytic Solutions for Verification and Convergence Analysis of Linear and Nonlinear Fluid-Structure Interaction Algorithms

Andreas Hessenthaler, Maximilian Balmus, Oliver Röhrle +1

Fluid-structure interaction (FSI) problems are pervasive in the computational engineering community. The need to address challenging FSI problems has led to the development of a br…

Multilevel convergence analysis of multigrid-reduction-in-time

Andreas Hessenthaler, Ben S. Southworth, David Nordsletten +3

This paper presents a multilevel convergence framework for multigrid-reduction-in-time (MGRIT) as a generalization of previous two-grid estimates. The framework provides a priori u…

Towards realistic HPC models of the neuromuscular system

Chris Bradley, Nehzat Emamy, Thomas Ertl +9

Realistic simulations of detailed, biophysics-based, multi-scale models require very high resolution and, thus, large-scale compute facilities. Existing simulation environments, es…
