Multi Environment The multi environment functionality allows for the definition of multiple environments, each with its own set of environmental conditions such as wave height, wave period, and wind speed. This is particularly useful for simulating scenarios where the environmental conditions change over time or for analyzing the response of a structure under different environmental conditions. Input parameters for the Multi environment include: Environment name: A unique name for each environment. Starting time: The time at which the environment starts in the simulation. Ramp duration: The duration over which the environment ramps up to its full conditions. It is recommended to set the ramp duration to set the ramp duration for at least 10 times the peak period. Ramp duration for first environment must be zero. The environments included in the multi environment definition must have the same structure. That is if the first environment includes a wave, current and wind, then all environments must include a wave, current and wind. Can only be applied for wave method Cosine or No wave, see see Dynamic calculation. Only supported for wind method State space model and No wind, see Dynamic calculation. Figure 1.
