 Superposition/Coupling of Wave and Current Inflow
-========================================
+=================================================
 For MHK turbines, wave and current velocities and accelerations are superimposed (i.e., summed) or coupled (see :ref:`sea-waves`) such that all submerged components are exposed
 to the same inflow field. Both AeroDyn and HydroDyn can query SeaState for wave field information. SeaState then queries InflowWind for the current
 field, sums or couples the velocities and accelerations, and returns the flow field information. This has several implications for modeling

 - For current only cases, set the SeaState wave field to 0; current information will be passed through SeaState from InflowWind

-Wave and current coupling is only possible when running the OpenFAST glue code or the AeroDyn driver. This feature is not supported by the HydroDyn or MoorDyn drivers.
