IHDHGridPoint Interface |
HD Storage point. Represents the volume between the Q-points before and after.
The HD H grid point contains water level (state) and volume.
Namespace: DHI.Mike1D.Engine.ModuleHD
Assembly: DHI.Mike1D.Engine (in DHI.Mike1D.Engine.dll) Version: 19.0.0.0 (11.1.1.1111)
SyntaxThe IHDHGridPoint type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | CourantNumber |
The Courant Number reflects the fraction between the amount of volume flowing
through the cell in one time step and the amount of volume of water in the cell.
If the value is larger than one, all the water in the cell is "replaced" during a single time step. |
| DischargeNph |
Discharge for time n+½
Unit: [m^3/s]
For internal grid points it is the average discharge between the upstream and downstream q grid point. For reach end grid points this is the time step average inflow/outflow to/from the reach (into/out off the grid point), used for mass balance. |
| FlowAreaNph |
Flow Area at time n+½ (crossSectional flow area)
|
| GridPoint |
Engine grid point matching this gridpoint
|
| SourcesInflow | Accumulated inflow sources (lateral inflow) at current time step. Always positive. |
| SourcesInflowAll |
Accumulated inflow sources (lateral inflow) at current time step. Always positive.
|
| SourcesOutflow |
Accumulated outflow sources (lateral outflow) at current time step. Always negative. It does not include SourcesOutflowSurface |
| SourcesOutflowAll |
Accumulated outflow sources (lateral inflow) at current time step. Always negative.
|
| SourcesOutflowSurface |
Accumulated surface outflow sources at current time step. Always negative.
This is water removed without component mass, typically evapotranspiration
|
| StorageWidthNph |
Storage width at time n+½
|
| SurfaceAreaNph |
Surface Area at time n+½ (storage area)
|
| VolumeError |
Volume error in time step
|
| WaterLevelN | Water level for time n. Unit: [m] |
| WaterLevelNp1 | Water level for time n+1. Unit: [m] |
| WaterLevelNpd | Water level for time n+delta |
| WaterVolumeN | Volume in grid point at time n |
| WaterVolumeNp1 | Volume in grid point at time n+1 |
Methods| Name | Description | |
|---|---|---|
 | AddSourceContribution | Add a source contribution to the HD H grid point. |
| CrossSectionUpdated |
Method that must be called when a cross section has an updated geometry
|
| GetVolume |
Volume in grid point for given water level.
Includes volume from additional storage/surface area.
