|---|---|---|---|---|---|
| LIMIT_AREA | nominal value | Whether and how calculations in the simulation should be limited to specific locations of the 3D world. | n/a |
There are a few modes available for the Water Module, dictating where calculations are to be performed:
- Entire map. Calculations are performed across the entire map. Water can flow anywhere.
- Limit to Water Areas Calculations are only performed in the locations where water areas are present.
- Limit to specific Areas Calculations are only performed in the locations where limitation areas are present.
Possible values
- 0: Entire map
- 1: Limit to Water Areas
- 2: Limit to specific Areas
Notes
- The overlay attribute name for this option is LIMIT_AREA, which is similar to the default Overlay key for Limitation areas.
- When any limit is in effect, water can flow between valid locations, even if those locations are defined through different relevant features (e.g. 2 adjacent water areas).
- In step 1 of the Water Overlay Wizard, the to be calculated area can be selected. When chosen for the option Limit to specified areas, an extra step in the wizard is added.
