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