Test cases from the dissertation of Benjamin Rodenberg

This repository contains modified versions of the tutorial cases from https://github.com/precice/tutorials/releases/tag/v202404.0. These tutorials acted as test cases for the PhD thesis "Flexible and robust time stepping forpartitioned multiphysics" of Benjamin Rodenberg in Chapter 6 "Test cases". The folders in this repository are related to the following (sub-)sections of the thesis:

• oscillator-overlap: 6.1 Oscillator problem:
  • Refer to oscillator-overlap/convergence_studies.sh for the experiments shown in Figures 6.1 and 6.2.
• partitioned-heat-conduction: 6.2 Partitioned heat conduction
  • Refer to partitioned-heat-conduction/convergence_study.sh for the experiments shown in Figures 6.4 and 6.5.
  • Refer to partitioned-heat-conduction/acceleration_study.sh for the experiments shown in Table 6.1.
• perpendicular-flap: 6.3.1 Perpendicular flap
  • Refer to perpendicular-flap/do_studies.sh for the experiments shown in Figures 6.6 and 6.7.
• turek-hron-fsi3: 6.3.2 FSI3 benchmark
  • Refer to turek-hron-fsi3/do_studies.sh for the experiments shown in Figure 6.8.

Please consider citing the preCICE distribution¹ or Benjamin Rodenberg's PhD thesis² if you find these tutorial cases useful.

You can use the workflows under .github/workflows to run the different tests cases via workflow dispatch.

Dependencies

The preCICE distribution version v2404.0 ¹ should provide a good basis for running the experiments provided in this repository. However, I suggest to use the latest versions of preCICE, respectively adapters. The experiments are known to run as expected on a system with the following specification:

preCICE components

• preCICE 8b5115e (temporary version, features will be released in upcoming v3.2.0 of preCICE); built with default CMake configuration.
• pyprecice 3.1.2 (automatically installed via requirements.txt of the respective case)
• FEniCS adapter 2.2.0 (automatically installed via requirements.txt of the respective case)
• OpenFOAM adapter 1.3.1
• deal.II adapter 4c6d092

OS and other dependencies

• Ubuntu 24.04
• Additional python packages (automatically installed via requirements.txt of the respective case)
• FEniCS 2019.2.0.64.dev0 (installed from FEniCS PPA https://launchpad.net/~fenics-packages/+archive/ubuntu/fenics; compare version provided by python3 -c "import dolfin;print(dolfin.__version__)")
• OpenFOAM 2412
• deal.II 9.5.1 (from https://launchpad.net/ubuntu/+source/deal.ii/9.5.1-2build3)
