A multirate Neumann-Neumann waveform relaxation method for heterogeneous coupled heat equations

A. Monge, P. Birken A multirate Neumann-Neumann waveform relaxation method for heterogeneous coupled heat equations DOI: arXiv:1805.04336 Abstract: An important challenge when coupling two different time dependent problems is to increase parallelization in time. We suggest a multirate Neumann-Neumann waveform relaxation algorithm to solve two heterogeneous coupled heat equations. In order to fix the mismatch…

On the convergence rate of the Dirichlet–Neumann iteration for unsteady thermal fluid–structure interaction

A. Monge, P. Birken On the convergence rate of the Dirichlet-Neumann iteration for unsteady thermal fluid-structure interaction DOI: doi.org/10.1007/s00466-017-1511-3 Abstract: We consider the Dirichlet–Neumann iteration for partitioned simulation of thermal fluid–structure interaction, also called conjugate heat transfer. We analyze its convergence rate for two coupled fully discretized 1D linear heat equations with jumps in the…
