  1. Beginning with Version 1.1c, three new features were added that are not described in the Users Manual:

    • A check of network connectivity is now made every time that a new hydraulic solution is computed during a simulation. A warning message will be generated if any group of nodes becomes disconnected from all sources of supply (due to closed pipes, pumps or valves).

    • You can now simulate the growth of a constituent up to a limiting potential, such as the growth of THMs (trihalomethanes) up to its formation potential. Simply add the following line to the [REACTIONS] section of the input data file:
               LIMITING POTENTIAL   xxx
      	
      where xxx is the maximum concentration possible. When used in conjunction with a positive reaction coefficient the rate of growth will be proportional to the difference between the limiting potential and the current concentration.

    • EPANET for Windows now has the capability to display a contour map for any node variable (e.g., pressure, head, water quality) at any time period of the simulation. To learn more about this feature, select Search for Help On from the Help menu and use "contour map" as the search topic.

  2. To enable the use of the 32-bit version of the EPANET simulator (for Windows 95/NT), add the following line to your AUTOEXEC.BAT file:
    		set epanet=32
    
    and re-boot your machine before running EPANET again. The 32-bit version of the simulator will only run on 386 or higher PC's. When used with EPANET for Windows 3.x/95/NT, it will only run when Windows is operating in Enhanced mode. It can use all available extended memory to analyze large networks and will run about twice as fast as the 16-bit version of EPANET.

  3. To increase the speed of the simulator when running under Windows by almost a factor of 2, you can use the Windows PIF Editor (usually found in the Main Program Group of Program Manager) to change the settings in the SOLVER.PIF file located in the EPANET directory. These changes will cause the simulator to run in full-screen mode rather than in a window. Before editing SOLVER.PIF, make a back-up copy of it in case you want to return to the slower windowed mode (some people may find the abrupt switch from Windows to full-screen DOS and back during an EPANET session disconcerting). Then launch the PIF editor, load in SOLVER.PIF, and change the following settings:

    1. Set Display Usage to Full Screen.
    2. Set Execution to Exclusive.
    3. Under Advanced settings, (a) Set Foreground Priority to 10000 (b)Un-select all Display Options.

  4. To replace the default editor that ships with EPANET with another DOS editor (such as the edit.com program that comes with MS-DOS 5.0 and higher):

    Use the Windows PIF Editor to change the settings in the EDITOR.PIF file in your EPANET directory. For example, to switch to the MS-DOS editor which resides in a directory named C:\DOS, use the following settings:

                    Program Filename:  C:\DOS\EDIT.COM
                    Window Title:      EDITOR
    

  5. To replace the default editor with a Windows editor, add the following section to the file EPANET.INI in your Windows directory (if this file doesn't exist then create it):
            [EDITOR]
            Program=
            Caption=
    
    where is the full path name of the editor program (e.g., c:\editors\winedit.exe) and window title is the portion of the caption that always appears in the editor's main window (e.g., WINEDIT).

    NOTE: To edit networks of any reasonable size, you should not use an editor with file size restrictions such as 64K (or 32K in the case of the Windows Notepad).

  6. It is possible to use Borland's Quattro Pro for Windows spreadsheet as an editor for EPANET. Add the following entries to the [EDITOR] section of your EPANET.INI file:
            Program=c:\qpw\qpw.exe
            Caption=Quattro Pro
    
       (Replace c:\qpw with the path to Quattro Pro if it is different.)
    
    You must name your data file with a .TXT extension so that Quattro Pro will interpret it as tab-delimited ASCII data. Likewise, you must save it to a file with a .TXT extension. Also, you must place all of your data on one page of a single notebook. It should also be possible to use Micrsoft Excel as an editor in a similar fashion.

  7. When you name a new file for input that currently does not exist, EPANET copies the contents of a file named TEMPLATE into it. This adds the names of the various input sections and data column headings to your input file. If you would rather work with a blank file, then simply rename the file named TEMPLATE in your EPANET directory to something else. Or you could edit the contents of TEMPLATE to customize the appearance of new EPANET input data files.
