SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| Unknown | 0 | The specified loss coefficient is interpreted as the outlet 'shape' coefficient Km | |
| Km | 1 | The specified loss coefficient is interpreted as the outlet 'shape' coefficient Km | |
| ContractionHLC | 2 | The specified loss coefficient is interpreted as the outlet 'contraction' coefficient eta_contr(j). This means that the model ignores the geometrical relations between the node and the outlet links (outlet shape), and applies the specified value directly as the eta_contr. The contraction losses in the outlet links are then computed by multiplying the velocity head in the respective link by the eta_contr. The total head loss for an outlet link is computed as a sum of the contraction, direction and elevation loss. | |
| TotalHLC | 3 | The specified loss coefficient is interpreted as the total outlet head loss. This means that the model completely ignores the geometry of the node/links, and applies the specified coefficient directly as the eta_out, the same for all outlet links at the node. The total head losses in the outlet links are then computed by multiplying the velocity head in the respective link by the specified eta_out. |
