## Release Notes for EPANET 2.3
|
|
|
|
This document describes the changes and updates that have been made in version 2.3 of EPANET.
|
|
|
|
- The check for at least two nodes, one tank/reservoir and no unconnected junction nodes was moved from `EN_open` to `EN_openH` and `EN_openQ` so that partial network data files could be opened by the toolkit.
|
|
- A `EN_setcurvetype` function was added to allow API clients to set a curve's type (e.g., `EN_PUMP_CURVE,` `EN_VOLUME_CURVE,` etc.).
|
|
- A `EN_setvertex` function was added to allow API clients to change the coordinates of a single link vertex.
|
|
- The index of a General Purpose Valve's (GPV's) head loss curve was added to the list of editable Link Properties using the symbolic constant name `EN_GPV_CURVE`.
|
|
- The `EN_getlinkvalue` and `EN_setlinkvalue` functions were updated to get and set the value of `EN_GPV_CURVE`.
|
|
- Negative pressure values for `EN_SETTING` are now permitted in the `EN_setlinkvalue` function.
|
|
- The `EN_STARTTIME` parameter was added into the `EN_settimeparam` function.
|
|
- The calculation of head loss gradient for low flow conditions was corrected.
|
|
- Improved updating and convergence tests were added to pressure dependent demand analysis.
