Container images

• Olivier Mesnard & Lorena A. Barba (2021). [Re] Three-dimensional wake topology and propulsive performance of low-aspect-ratio pitching-rolling plates (container images).

The deposit (4.7GB) contains the Docker and Singularity images used for the replication:

• petibm-rollingpitching_PetIBM0.5.1-xenial.tar: tar archive of the Docker image mesnardo/petibm-rollingpitching:PetIBM0.5.1-xenial which includes the PetIBM application for the 3D rolling and pitching wing
• petibm-rollingpitching_PetIBM0.5.1-xenial.sif: Singularity image (build from the Docker image) that was used to run the simulations on the pegasus HPC cluster (at the George Washington University)
• petibm-rollingpitching_prepost.tar: tar archive of the Docker image mesnardo/petibm-rollingpitching:prepost which contains all tools to pre- and post-process the numerical outputs of the simulations

We used Docker 1.39 (see version info) and Singularity 3.4.2.

Software/Hardware requirements

The following list of libraries and tools should be installed on the host machine to be able to run the Singularity image:

• CUDA Toolkit 10.1
• Singularity 3.4+
• OpenMPI 3.1.4

The NVIDIA AmgX library contained in the Docker image mesnardo/petibm-rollingpitching:PetIBM0.5.1-xenial was compiled with CUDA Toolkit 10.1 to target NVIDIA GPUs with a compute capability of 3.5 (Kepler - Tesla K20, K40), 3.7 (Kepler - Tesla K80), 6.0 (Pascal - Tesla P100), and 7.0 (Volta - Tesla V100).

Note we used NVIDIA V100 GPUs to solve the pressure Poisson system in our simulations; the two other linear systems were solved on CPUs with the PETSc library. If no GPUs are available on the host machine, one should still be able to use the same Docker or Singularity image and solve the Poisson system on CPUs. Otherwise, one should be able to launch and configure an AWS EC2 instance following these instructions.

Reproducibility packages

Download the Zenodo archive (18.6 GB) with the primary data output from PetIBM.

| :warning: WARNING | |:-| | Generating secondary data (e.g., 3D vorticity field) requires a machine with more than 16 GB of memory (32 GB is recommended). If you do not have access to such machine, one solution is to launch a t3.2xlarge EC2 instance on AWS and run the Docker container there (see instructions). |

Generate all secondary data and figures of the manuscript (~20 minutes):

shell cd repro-packs docker run --rm -it -v $(pwd):/postprocessing mesnardo/petibm-rollingpitching:prepost /bin/bash /postprocessing/scripts/generate_all_figures.sh > repro-packs.log 2>&1
