MeanWindCell

public MeanWindCell(Field windProfile,
                    Field densityProfile)
             throws VisADException,
                    RemoteException

Constructs from a wind profile and a density profile.

Parameters:

MeanWindCell

public MeanWindCell(DataReference windProfileRef,
                    DataReference densityProfileRef,
                    DataReference meanWindRef)
             throws VisADException,
                    RemoteException
