IHDNode Interface

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.

EngineNode matching this module node

List of Reach connections, each specifying a connection between the node and a reach.

Accumulated inflow sources (lateral inflow) at current time step. Always positive

Accumulated outflow sources (lateral outflow) at current time step. Always negative. It does not include SourcesOutflowSurface

Accumulated surface outflow sources at current time step. Always negative.

Accumulated surface outflow sources at current time step. Always negative This is water removed without component mass, typically evapotranspiration

Calculate the volume/mass error for node. In volume unit ([m3]).

Water level at time n

Water level at time n+1

Lateral inflow, average value over time step or value at time N+½.

Be aware that you can not add lateral inflow to a node which is an active open boundary (has no effect).

After a HD time step (and before AD time step), it is possible to add or withdraw discharge from both source input and output.

The amount must be smaller than both SourcesInflow and SourcesOutflow, or, it will be limited to the largest of the two (because they cannot change sign)

Add to "offers", i.e. quantities that can be outputted to result file and requested through the result proxy system
