IAdvancedBoundaryItem Interface

An advanced boundary item adds functionality for scale factor, soft start (gradual start-up) and application interval to the standard IBoundaryItem

Namespace:  DHI.Mike1D.BoundaryModule
Assembly:  DHI.Mike1D.BoundaryModule (in DHI.Mike1D.BoundaryModule.dll) Version: 19.0.0.0 (11.1.1.1111)
Syntax
public interface IAdvancedBoundaryItem : IBoundaryItem

The IAdvancedBoundaryItem type exposes the following members.

Properties
  NameDescription
Public propertyApplicationBegin
Start datetime of the application of the item.

If user specified values are set, remember also to set the UseApplicationInterval

Remarks
If UseApplicationInterval is false, this is set automatically during prepare phase to either
  • Globally: Simulation start time
  • Locally: Item source start time (typically timeseries file start)
Public propertyApplicationEnd
End datetime of the application of the item

If user specified values are set, remember also to set the UseApplicationInterval

Public propertyEumQuantity
EUM quantity of boundary item.

Used for validation and in AD also for unit conversion.

(Inherited from IBoundaryItem.)
Public propertyIsDryWeatherFlow
Boundary items can be marked as "dry weather flow" (used in MIKE URBAN). This is used in Long Term Simulation to exclude dry weather flow from the total inflow when evaluating how to start a new LTS job (if selecting a new hot start file)

This flag has no effect on the simulation, only on LTS job evaluations.

(Inherited from IBoundaryItem.)
Public propertyScaleFactor
A factor by which values are scaled. Default 1.0.

Only valid for certain item types, e.g., load/inflow types, not for types like waterlevel.

Public propertySoftstartDuration
Duration of softstart period. Default 0
Public propertySoftstartType
Type of softstart. Default none

Softstart does not make sense for all boundary types, typically only for those that otherwise can be disabled/left out of the simulation.

Softstart starttime is ApplicationBegin which if not set explicitly is either
  • Globally: Simulation start time
  • Locally: Item source start time (typically timeseries file start)
Public propertySoftstartValue
Softstart initial value. Default 0.0
Public propertyUseApplicationInterval
Boolean specifying whether the application of the item is limited in time

Set this flag if user specified values of ApplicationBegin and ApplicationEnd is to be used. If this flag is not set the application begin and end time will be overwritten/controlled by the Boundary Data, set in Prepare(DateTime, DateTime, IDiagnostics) or by the individual boundary item.

Methods
  NameDescription
Public methodGetAccumulatedValue

Get boundary value accumulated over the specified period.

It is the callers responsibility to check if the item is applicable at the given datetime before calling GetAccumulatedValue.

If the item is only applicable over a part of the interval, it must return the accumulated value for that part of the interval.

(Inherited from IBoundaryItem.)
Public methodGetNextTransitionTime
Gets the next time for which there is a different value in the boundary item.
(Inherited from IBoundaryItem.)
Public methodGetValue

Get boundary value at specified date/time.

It is the callers responsibility to check if the item is applicable at the given datetime before calling GetValue.

(Inherited from IBoundaryItem.)
Public methodIsApplicable(DateTime)
Checks whether the item is applicable at the given datetime.
(Inherited from IBoundaryItem.)
Public methodIsApplicable(DateTime, DateTime)
Checks whether the item is applicable at the given time interval. It returns true also if the item covers only a part of the start-end interval
(Inherited from IBoundaryItem.)
Public methodPrepare
Prepare item for simulation.
(Inherited from IBoundaryItem.)
Public methodValidate
Validate this
(Inherited from IBoundaryItem.)
