H2020 OPERA Project – Mutriku database

As part of the OPERA H2020 project, the Mutriku Wave Power Plant is being used as a real condition laboratory for the experiment of innovative technologies. The plant is situated in the Basque Country and has been operating since 2011.

This repository publishes the IST Biradial turbine operating data collected at the Mutriku wave power plant from July 2017 to June 2018 within the framework of WP4.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 654.444.

BEMRosetta

Boundary Element Methods are extensively used to model hydrodynamic forces in offshore devices like ships, offshore wind platforms and wave energy converters. These solvers use device geometry mesh to get some hydrodynamics coefficients as radiation damping, added mass, wave diffraction force, and wave excitation force. All these data is saved in file formats incompatible between them. These may avoid to use the coefficients between programs.

BEMRosetta allows to load the hydrodynamic coefficients from a format saving it in another. In addition it allows to compare the results obtained between programs, the results between similar geometries and the same geometry with different discretization levels.

In addition, BEMRosetta allows to view and visually compare the meshes from different programs.

BEMRosetta runs on Windows and Linux, it is done in C++ so install is simple, and it includes a GUI and a command line version.

Actually, BEMRosetta opens files from:

  • Wamit: .out, .3sc, 3fk, .1, .3, .4, .hst
  • Nemoh: Nemoh.cal, Mesh/Hydrostatics*.dat, Mesh/KH*.dat, RadiationCoefficients.tec, ExcitationForce.tec, DiffractionForce.tec, FKForce.tec, IRF.tec
  • FAST-Wamit: HydroDyn.dat, .1, .3, .hst
  • SeaFEM-Nemoh: .flavia.inf, RadiationCoefficients.tec, ExcitationForce.tec, DiffractionForce.tec, FKForce.tec
  • Ansys AQWA: .LIS, .AH1
  • COER FOAMM: .mat

BEMRosetta is free source. You can find all the code and resources in the Github page.
