SIC^2: Simulation and Integration of Control for Canals
Scenario and variant: operating instructions
In a scenario, all the data needed to launch a calculation in steady or unsteady flow are defined. Variant (of a scenario) will allow to overwrite some parameters of the scenario while keeping the data as a reference scenario for all non-modified settings.
Changing the settings modified by the variant is only possible in the variable management table.
The following table defines where items of the hydraulic mode can be set:
| Item | Scenario | Variant |
|---|---|---|
| Calculation settings: | ||
| —> Steady or Unsteady flow | X | |
| —> Time | X | |
| —> Results writing | X | |
| —> General settings | X | |
| Nodes description: | ||
| —> Create, delete offtakes | X | |
| —> State of the offtake (Active / Inactive) | X | X |
| —> Modify the type of the downstream boundary condition | X | |
| —> Modify water elevation or discharge of downstream boundary condition | X | X |
| —> Create, delete, modify type of devices at offtakes | X | |
| —> Modify characteristics of devices (width, sill elevation, opening...) | X | X |
| Cross-structures description: | ||
| —> Create, delete, modify type of devices | X | |
| —> Modify characteristics of devices (width, sill elevation, opening...) | X | X |
| Roughness (Manning) and infiltrations | X | |
As an unsteady flow calculation requires an initial condition, it is advisable to perform the various simulations (steady and one or more unsteady flow) in a scenario and create a variant by unsteady flow simulation you want to perform.
