Replication Data for: A Waveform Iteration Implementation for Black-box Multi-rate Higher-order Coupling

This repository contains all the data needed for performing the experiments and producing the plots from "A waveform iteration implementation for black-box multi-rate higher-order coupling" ¹.

It is a fork of https://github.com/BenjaminRodenberg/test-cases-dissertation with test cases from Benjamin Rodenberg's dissertation "Flexible and robust time stepping for partitioned multiphysics" ². The test cases are modified versions of the tutorials from https://github.com/precice/tutorials/releases/tag/v202404.0 ³.

The following two folders from this repository allow to run the experiments and create the plots from the paper:

• experiments: The definition of the setups and scripts to execute the experiments. The structure of this folder closely follows https://github.com/precice/tutorials/releases/tag/v202404.0.
• plotting: Scripts for creating plots from the data produced by the experiments. This folder also contains pre-computed data obtained by running the scenarios from experiments.

Both folders contain subfolders corresponding to the following subsections of the paper:

• oscillator-overlap: 4.1 Partitioned oscillator
• partitioned-heat-conduction: 4.2 Partitioned heat conduction
• perpendicular-flap: 4.3 Perpendicular flap

If you want to run the experiments, please refer to experiments/README.md for further instructions. If you want to create the plots from given results, please refer to plotting/README.md.

Running the experiments and creating the plots with GitHub Actions

The following folders contain job definitions and Dockerfiles that allow to run the experiments and create the plots using GitHub Actions. You can ignore these folders if you want to run the experiments locally.

• .github/workflows: Definition of pipelines that allow to perform the experiments using GitHub Actions. You can fork this repository to run the experiments and create the plots with GitHub Actions.
• tools/docker: Docker files used by the CI job .github/workflows/publish-docker.yml to create docker images for running the experiments. The docker images can be found under https://hub.docker.com/r/benjaminrodenberg/fenics-openfoam and https://hub.docker.com/r/benjaminrodenberg/precice-openfoam.
