In this tutorial you have been introduced to the possibilities for RAO and Drift coefficients in AquaSim.

In the first case study, response amplitudes were assigned to displacement. A node was forced to move as described by translatory amplitudes in a table. In the second case, the table was reused but applied to loads. Instead of translations, the node was given amplitudes in terms of force and moment. From this one could see that RAO on displacement and load works in the same manner. The last case introduced drift coefficients. The node was assigned drift coefficients as a function of wave periods.

As there are many parameters in the presented tables for RAO and Drift coefficients, the user is encouraged to start with a simple model and stepwise apply parameters to build understanding for how it works.
