OWA:EPANET 2.3.1

This patch release restores the ability to assign an initial status of fully open to a valve and corrects how the setting of a Positional Control Valve is changed using the API or with a control.

OWA:EPANET 2.3

Version 2.3 adds some useful new features to the previous release of OWA-EPANET. These additions include:

• a Positional Control Valve whose loss coefficient is determined by its percent open setting.
• a Fixed And Variable Area Discharge (FAVAD) model to compute pressure-dependent pipe leakage
• the ability to enable or disable simple and rule-based controls
• a Flow Balance report listing the components of a system's total inflow and outflow
• the option to use an expanded set of pressure units independent of the unit system in place
• the ability to edit EPANET's Tag property
• an API binding for C#
• improved support for using the API as a database editor for graphical user interfaces.

In addition some existing features were improved and a number of bugs were fixed. Please consult the ReleaseNotes2_3.md file for the full list of updates. Updated documentation of the API for this new version of the OWA-EPANET Toolkit can be found here.

OWA:EPANET 2.2

Version 2.2 represents some major improvements over the first community release of EPANET. Some highlights:

• includes a full set of functions to set and retrieve values for all parameters contained in a network model
• networks can be built programmatically; completely from function calls instead of from an input file
• multiple projects can be analyzed in parallel in a thread-safe manner
• the ability to use pressure dependent demands in hydraulic analyses
• more robust results with regard to hydraulic convergence, low/zero flow conditions, and water quality mass balance
• faster run times for single period hydraulic analyses.
• the updated DLL will work with the current GUI released by US EPA.
