Environment An environment defines the wave, wind, and current condition used in the simulation. Multipe environments may be defined in a model, but only one is used during simulation. The active environment in a simulation is selected in the condition editor. The following options are available: Wave: Defines the main wave in the sea state. See Waves. Swell: Defines an optional secondary wave in the sea state. See Waves. Wind: Defines the wind condition. See Wind. Current: Defines the current condition. See Current. Location Current
