Clicking the 
icon adds an Ocean Current object to the
Static Structural analysis.
Alternatively, you can right-click the Static Structural analysis and select > from the context menu.
You may define any number of Ocean Current objects in your analysis, provided that the Static Structural system is linked to a Hydrodynamic Diffraction system (not a time domain Hydrodynamic Response system). However, they will only have an effect on the calculation if they are selected in the Include Current field of the Hydrodynamic Pressure object.
Use the Velocity and Direction property to set the way in which the current is defined. The available options are:
Simplified Definition: Current is defined by a constant current Speed and Direction
Advanced Definition: Current is defined by varying Speed and Direction values at specified Depth increments in the Advanced Current Definition tabular data input. Click the
icon to add more rows to
the table.
