Feature or improvement description
SeaState has three sub-models for current. From readthedocs:
In my case, I wanted to use only the depth-independent sub-model. So, I defined the input file as follows:
However, OpenFAST aborted complaining that the near-surface current reference depth (CurrNSRef) [sub-model that I'm not using] had to be greater than zero.
This is because SeaState is using an internal logic that checks some input parameters even if there any not used.
The proposed change should fix this by using a logic that applies only if the user is using the near-surface sub-model. For example: checking for the near-surface current reference depth, only if the near-surface current velocity at still water level is different than zero.
