TEAMER: CFD Simulation Datasets of Dehlsen Associates' Centipod Wave Energy Converter

This directory contains data-sets pertaining to the Computational Fluid Dynamics (CFD) modeling of Dehlsen Associates, LLC "Centipod 1P6" (C1P6) two-part point absorber wave energy converter (WEC) by Sandia National Labratory. This project is part of the TEAMER RFTS 11 (request for technical support) program.

Simulations were developed in OpenFOAM, utilizing the waves2Foam library for waves generation and absorption, the MoorDyn v2 library for mooring, and the rigidBodyDynamics library in OpenFOAM for simulation of the two-body system. Custom restraint models were developed for two-body braking and end-stops, and custom code for these models is included in this directory.

Overview of contents in the directory:
(1) Simulation input decks (in 'simulation_input_decks')
- Cases included are waves-only and two-body + waves simulations for the two wave cases of interest

(2) Post-processed output ASCII data from the simulations, which includes (in 'simulation_output_data_and_scripts')
- Wave probe measurements of the free surface elevation of the water - 6 DoF motion of both devices - 6 DoF hydrodynamic forces on both devices
- Forces related to the two-body braking and endstop models
- Relative motion between devices
- Pressure probes along the Pod
- Forces and normals distributed across the Pod -- this data is created via ParaView Filtering of raw simulation data
- Scripts for plotting the output data in each subfolder under 'scripts'
- Note: in the case of 2body_with_waves, there is a README.md file included which explains each of the types of output files and shows example plots

(3) Useful bash and/or python scripts used for post-processing of raw simulation data (in 'simulation_post_processing_scripts')

(4) Files related to custom code developed for the projects (in 'custom_code')

(5) Description of the models implemented for DA's braking and end-stop system (in 'braking_models_description')

(6) Output animations for two-body device motion under each wave condition (in 'animations')
