Flags meaning
Meaning of the codes "Error flag" at the offtake
The error flag at the offtake is used to control the results of a target discharge regulation at an offtake. Its meaning is as follow:
| Code | Meaning |
|---|---|
| -4 | Non convergence |
| -3 | Downstream elevation superior to upstream elevation (the offtake is closed!) |
| -2 | Sill elevation or downstream weir elevation superior to the upstream elevation |
| -1 | The required discharge cannot be satisfied |
| 0 | The required discharge is null (the offtake is closed!) or there are no regulation at the offtake |
| 1 | The required discharge is satisfied |
Meaning of the codes "Error Flag" at a section
The error flag (IF1 variable in results and/or XML file) has the following meanings:
| Code | Meaning |
|---|---|
| 10 | Targeted water elevation at the regulator < downstream water elevation |
| 9 | Targeted water elevation at the regulator too high |
| 8 | Targeted water elevation at the regulator too low |
| 7 | Non convergence of regulator calculation |
| 6 | Device oversized relative to the geometry of the river (water depth < critical depth) |
| 5 | The surface width varies too quickly: unaccuracy calculation. Froude number is >1 while the calculation is located on a branch of the specific head HS(Y) |
| 4 | Large variation of elevation after calculation with small steps and slope of the water line still steep |
| 3 | Water line slope steep with small steps calculation |
| 2 | Passing by the critical depth in the first section |
| 1 | Subcritical flow |
| 0 | Supercritical flow |
| -1 | Water elevation less than bottom elevation |
| -2 | Enormous water level in the section |
| -3 | Non convergence of critical depth calculation |
| -4 | Negative discharge in the section |
| -5 | Non convergence of water level calculation |
| -6 | Non convergence of cross-structure calculation |
Meaning of the "Type of flow" codes at a device
The type of flow (ITEC variable in the XML file) has the following meanings:
| Code | Meaning |
|---|---|
| -2 | Free flow, open surface flow |
| -1 | Submerged flow, open surface flow |
| 0 | Nil flow rate |
| 1 | Free flow, piped flow |
| 2 | Submerged flow, piped flow |
| 8 | Free flow, open surface flow with overflow |
| 9 | Submerged flow, open surface flow with overflow |
| 11 | Free flow, piped flow with overflow |
| 12 | Submerged flow, piped flow with overflow |
Meaning of "Gec gates errors" codes at a device
The error codes of the GEC gates (IERR variable in the XML file) has the following meanings:
| Code | Meaning |
|---|---|
| 0 | OK |
| -1 | J = Z1-Z2> JM for AVIS gates |
| -2 | Closed gate - Water level below the level to be regulated - Increase Z1 (AMIL) or Z2 (AVIO / S) |
| -3 | Fully opened gate - Water level above the level to be regulated - Decrease Z1 (AMIL) or Z2 (AVIO / S) |
| -4 | Gates AMIL, ZMAX is not between 0 and D |
| -5 | If R=<0 or HA-ZR>R or D=<0 or H=<0 or HA-H-ZR<-R (all gates except mixed gates) |
| -5 | If R=<0, D=<0 or H=>0 (all mixed gates) |
| -6 | AMIL with overflow (Z1>ZR+W+EC) |
| -7 | Problem with the targeted flow too high for the selected gate |
| -8 | AVIO with overflow (normally case not possible) |
| -9 | AVIS with overflow (Z1>ZR+W+EC) |
| -10 | If J = Z1-Z2 <0 |
