BoundaryItemQH Class

Create Q-h boundary item with specified size of Q-h table

Start datetime of the application of the item.

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

End datetime of the application of the item

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

EUM quantity of boundary item.

Used for validation and in AD also for unit conversion.

Data from an extended DataContract not recognized here

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.

Q(h) table of values. X is h and Y is Q.

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.

Duration of softstart period. Default 0

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)

Softstart initial value. Default 0.0

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.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Not implemented. QH boundaries are used by directly accessing the Qh table

Serves as the default hash function.

Default implementation of GetNextTransitionTime(DateTime) returning the incoming datetime as the next transition time

Gets the Type of the current instance.

Not implemented. QH boundaries are used by directly accessing the Qh table

Checks whether the item is applicable at the given 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

Creates a shallow copy of the current Object.

Prepare item for simulation.

Set values to Q-h table at specified index

Weights the accumulatedValue with the hot-start value.

Calculate the strength factor of the softstart. Uses _applicationBegin as the startup Usage: a = SoftStartFactor(t); Value = (1-a)*_softstartValue + (a)*Value;

Returns a string that represents the current object.
