DHI.Mike1D.Engine Namespace

Use CalculateDistances(ILocation) to start a calculation, and extract data from Distances.

It can also connect boundaries to XXX, for creating an LTS job list where EngineNet and HD is not required.

It handles both live catchment values and values from RR result files.

NOTE: This should be the only component depending on the dataaccess components, especially the NetworkDataAccess classes.

If desired, this can be moved to another project, to remove dependencies from EngineNetwork to DataAccess components.

An outlet is the only type of open boundary that does not need a boundary condition

An outlet can have a boundary condition (water level/QH), in which case the water can also flow into the system.

The list does not allow nodes with the same id.

Digipoints are found in the LocationSpan

If storing a large amount of data in each span, consider instead one of the NetworkDataT classes. This class is a light-weight version of the NetworkDataT implementation.

It does fast lookup in a dictionary of span-id's, containing a list of spans for each id, and it does linear searching in the chainages.

Within a routing element the incoming discharge can be routed by different methods specified in the RoutingMethod. All incoming discharge into the element is routed by the method (i.e. an inflow point source will have the same effect regardless of where in the routing element it is connected).

A routing reach contains a number of Elements which defines routing method, and optionally how to calculate water levels. It also contains a number of RoutingGridPoint in the GridPoints list. There may be more grid points than routing elements.

It contains itself a list of check points, where check points can be added, CheckPoints.

It also contains a list of ITimeCheckPointSet, CheckPointSets, in case a user implementation of a check point set is appropriate (e.g. constant equidistant check points)

All check points within the list of check points and the list of check point sets will be considered as check points.

The weir is characterised by a length (WeirLength) and a width (WeirWidth).

Based on the article of Oliveto, Giuseppe. (1998). "Sewerage overflows: new researches on bottom openings and side weirs". Excerpta. 12. 251-281.

The class handles two types of inflow, surface inflow and catchment runoff inflow. The procedure models that the catchment runoff inflow "runs through" the surface model before entering the node.

Excess catchment runoff (larger than the MaxInflowFromSurface) is retained in the WaterVolumeInReservoir ([m3]). When a surface model is present, the coupling procedure must transfer the reservoir volume to 2D model and empty this reservoir by calling EmptyReservoir.

The net inflow to the combined system is CatchmentQ. On top of that there may be an exchange of water between 1D and 2D. The CatchmentQ is split into three parts CatchmentQ = ActualCatchmentInflow + CatcmentQRoutedToSurface + WaterVolumeInReservoir/dt where 1) goes into the network, 2) is routed to the surface (when surface model is present), and 3) is what is left due to max inflow limit.

Inflow to MIKE 1D: q_in_1D = ActualSurfaceInflow + ActualCatchmentInflow Inflow to 2D: q_in_2D = -ActualSurfaceInflow + CatcmentQRoutedToSurface + WaterVolumeInReservoir/dt

Class for easing handling of proxies, and providing proxy functionality for the entire EngineNet, spanning quantities from all its modules.

There is a routing grid point in the end of every EngineRoutingElement.

A checkpoint is a point in time which the engine must hit exactly.

A node structure must have three reaches connected, and the 3rd reach is a special reach where the discharge into the reach is controlled by the CalculateDischarge(DateTime) method.

Current usage is adding a source that depends on the water level, and including a water level derivative to take the change of water level into account, i.e. Q_s = Q_s^n + dQdh * (H^{n+1} - H^n)

The actual source added can be calculated using the Evaluate method after the time step has finished (at the PostTimeStepEvent).

Defined as flag so they can be used as selection, i.e. GridPointTypes allow = HGridPoint | QGridPoint
