Welcome to Nemoh-Workshop!
==========================

The aim of this lab work is to become familiar with a linear potential flow solver for the diffraction-radiation loads acting on a floating structure.
To this end, the Boundary Element Method (BEM) code NEMOH is used on the simple test case of a free floating buoy in infinite water depth.
NEMOH is open-source, developed at Centrale Nantes and available on `GitLab <https://gitlab.com/lheea/Nemoh>`__.
As many other BEM solvers (WAMIT, DIODORE …), NEMOH can be used to compute a hydrodynamic database using linear potential flow theory.
This database gives hydrodynamic coefficients, such as added-mass, damping and excitation force in frequency domain.
It is then possible to compute the motion of such a system in time-domain in various environmental conditions.

During these lab work sessions, the goals are to:

- Set-up a calculation for NEMOH
- Generate a converged mesh for the linear potential flow solver Nemoh
- Understand the characteristics of the radiation and diffraction loads for different wave frequencies.
- Solve the equation of motion of the cylinder in waves to compute its motion transfer functions (RAO for Response Amplitude Operator)
