This command is inactive unless a cell string is selected. It allows the user to assign a boundary condition to the cell string through the M2D Boundary Conditions Dialog.
Boundary conditions specified within this dialog include:
Unassigned Boundary: When a cell string is created, the string receives this assignment. This is not a boundary condition, but rather indicates that the boundary has not been assigned yet and still needs to be.
Flow Rate-forcing: A time series must be defined (by clicking the Define Curve… button) that contains a list of times and flow rates in m3/sec along the boundary.
WSE-forcing: A time series must be defined, just as it must for the flow rate-forcing boundary. The time series associated with this boundary contains a list of times and water levels in meters along the boundary. The Interpolate between times checkbox affects how the time series data is used within M2D when forcing a boundary, whether only absolute values are used, or if interpolated values are also used.
Tidal Constituent-forcing: Uses up to eight tidal constituents to force with. Tidal constituents are specified within the M2D Tidal Constituent dialog accessed in the Model Control dialog.
Open, non-forcing: Assigned along an ocean boundary when forcing is either unknown or undesired. Water can move across this boundary.
The file browse button allows the user to load an already-existing time series for use with one of the time series boundary conditions.
