.. Computational domain generation
.. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. In order to generate a good quality computational domain, it is advisable to the user to follow the following recommendations:

.. - For the case where no currents are imposed, the most indicated shape for the computational domain is a cylinder.
.. - A region with higher mesh resolution in the free surface close to the floating object is usually needed in order to correctly capture the scattered waves solution (waves radiated and diffracted by the floating object). Hence, it is usually advisable to generate a surface surrounding the floating body where a smaller mesh size will be further assigned. Such a region shall usually roughly coincide with the analysis area (i.e. the region where no artificial absorption is introduced).
.. - When simulating wave spectra with multiple waves, the absorption area should be at least as long as the maximum wave length. Recommended length is twice the maximum wave length. Nevertheless, if monochromatic wave is used along with Sommerfeld radiation condition, the absorption area might be reduced to half the wave length.
.. - Computational depth should be no larger than physical depth.
.. - If simulating infinite depth, it is advised to set the computational depth to the maximum wave length.
.. - Computational depth might be smaller than physical and/or recommended if the bottom boundary condition is used. Care must be taken since the depth of the body should be small compared to the computational depth when using this option.
