v0.2

Ocean Engineering Toolbox v0.2

Pre-release of OET v0.2. Capable of simulating a single, floating body in unidirectional seas. Generates the wave elevation profile using 3 spectral options and estimates the wave excitation force.

• User selects between regular or irregular wave elevation profiles
• Irregular profiles can be generated for the Pierson Moskowitz, Brettschneider, and JONSWAP single-peak spectra
• Excitation force implemented as a spectral decomposition of the elevation data for a user-defined number of frequency components
• Excitation coefficients (real and imaginary), state space matrices, and model's hydrostatic data must be input via a MATLAB struct
• Results validated against the WEC-Sim tool
• ZIP folder 'tutorial' includes an example simulation

v0.1

Ocean Engineering Toolbox v0.1

Initial pre-release of the OET. Capable of simulating a single, floating body in unidirectional seas.

• Wave excitation force is input as a user-specified discrete vector
• No support for the wave elevation profile or generating the excitation force
• Radiation force implemented as a state space formulation of the convolution integral
• State space matrices must be input via a MATLAB struct
• Results can be validated against a user-defined dataset (heave velocity and radiation force)
• Results can be compared against a frequency-independent representation of the motion

Despite limited functionalities, this project serves as a proof-of-concept Modelica library to explore whether the symbolic simulation of wave energy converters is feasible and efficient. Documentation included in the source code.
