Run

The Run menu contains options for calculation, validation and simulation of model components.

Recalculate flow conditions

The Q/h relations of structures (weirs and culverts) must be recalculated if any changes are made to the structures and/or the up/down-stream cross sections.

Only structures where the flag ‘Allow for recalculation’ has been enabled will be recalculated.

Extended validation

Before running the model, it is recommended to run an extended validation of the model setup. Any validation issues will be shown in the Validation window see section Validation (p. 26).

Simulation

To execute the model engine, select ‘Simulation’. Output from the computa­tional engine (status and error messages) are shown in the Simulation win­dow see section Simulation (p. 26).
