There are two subroutine of realization of the fields in the code. One is RealizeProvided and second one is RealizeProvided and other is RealizeAccept. RealizeProvided would realize fields which is willing to provide grid, i.e. DART is willing to provide grid for those fields and RealizeAccept is where realization of field is happening who are accepting grid from ocean model component.
