NAME
modflow-gui - Preprocessor and postprocessor graphical-user
interfaces for preparing MODFLOW-96, MOC3D, MODPATH,
and ZONEBDGT input data and viewing model output for
use within Argus Open Numerical Environments (Argus ONE)
ABSTRACT
MODFLOW-GUI is a graphical preprocessor and postprocessor for the
U.S. Geological Survey modular, three-dimensional, finite-
difference, ground-water flow model (MODFLOW-96), solute-
transport model (MOC3D), particle-tracking postprocessing model
(MODPATH). MODFLOW-GUI, and subregional water budget program
(ZONEBDGT) is implemented as plug-in
extensions (PIEs) for use with Argus ONE version 4.20, revision m or
later. Although Argus ONE runs on a variety of computing platforms,
the MODFLOW-GUI PIEs are only available for systems running
Microsoft Windows 9x or NT.
Note: The Argus ONE interface only works with MODFLOW-96 and not
with earlier versions of MODFLOW.
MODFLOW-GUI supports the following packages: BAS5, BCF5,
WEL5, RIV5, DRN5, GHB5, RCH5, EVT5, SOR5, SIP5, PCG2, DE4,
STR1, HFB1, FHB1, MOC3D, MODPATH, and ZONEBDGT.
The following capabilities are NOT yet supported:
CHD1, IBS1, RES1, TLK1, and GFD1.
HISTORY
Version 3.1.2.0 00/02/07 Fixed display of the "About" dialog box in Budgeteer on
computers using large fonts. Warning message is displayed
if the user does not have permission to write
LastTemplate.met to the directory where the MODFLOW GUI
is installed. Fixed bug in export of stream diversion numbers.
Corrected error in expressions for locations of drains and
rivers specified with point contours.
Version 3.1.1.0 99/12/30 Corrected misspelling in Edit Project Info dialog box.
Corrected bug in Budgeteer that prevented column titles
from being written to a file except in the first zone
Fixed corrupted help file.
Version 3.1.0.0 99/11/08 Fixed bug in export of river package when alternative export
template was used. Made addition of new layers faster.
Fixed bug in cancelling Edit Project Info dialog box. Added
support for new capabilities in MOC3D 3.0
Version 3.0.14.0 99/10/03 Fixed bug in export template for MODPATH that would cause
it to produce incorrect input files if the parameter order
was changed. Fixed bug in JoinFiles PIE that would prevent
files from being renamed properly if a file with the new
name already existed. Changed List PIE to allow it to invert
all the members of a 3D list even if some of the members
were equal to zero. Increased speed at which new layers are
added to a project by the MODFLOW GUI.
Version 3.0.13.0 99/09/03 Added new parameter to Grid (Prescribed Concentration Unit[i])
to improve the way in which MOC3D concentrations are exported.
Version 3.0.12.0 99/09/02 Fixed bug that caused EVT parameters to be exported
incorrectly if the order of the parameters was changed.
Installer no longer installs ctl3d32.dll. This must be
installed manually on Windows NT 3.51. It is not required
for Windows 95 or Windows NR 4.
Version 3.0.11.0 99/08/20 Fixed bug that caused MOC3d flow vectors to
be reversed under some circumstances.
Version 3.0.10.0 99/08/20 Fixed bug that prevented the editting of FHB times under
some circumstances.
Modified Hydrograph Extractor to support reading MOC3D,
MT3D, and SUTRA files.
Fixed bug in expression for MODFLOW FD Grid.Initial Head Unit[i]
when the "Average Points and Open Contours" method is used.
Fixed bug in export of wells when vertical discretization is
greater than 1.
Version 3.0.9.0 99/08/10 Fixed bug in code for inserting new stress periods.
Modified Hydrograph Extractor to support reading
large data files under Windows 95.
Version 3.0.8.0 99/08/04 Added Point Rivers and Point Drains. Fixed bug that
prevented the "Time-varying constant concentrations"
check box from working properly in the customized version
Fixed bug that set the status bar color to the wrong
color in the customized version. Added warning about
model paths that may not be exported correctly by Argus
ONE because they contain "\n".
Fixed bug that allowed users to include blank spaces in
the root names of files. Changed name of choice for
"Method for assigning the IBOUND parameter and prescribed
heads in the initial head MODFLOW FD Grid parameter" from
"Method from MF-GUI versions 1 and 2" to "Method from MF-GUI
version 2" because those methods were different. Fixed bug
that would cause Argus ONE to crash if a MOC3D subgrid was
used on a computer in which the regional settings specified
that a character other than "." was used as the decimal
separator.
Fixed bug in customized version so that user can choose
not to export data for some MT3D packages. Eliminated locks
on the MT3D Postprocessing layers.
Table headings in the Inport Wells form can now be
rearranged. To do this, click on a heading and move it
to a new position.
Minor bug fixes in customized version of MODFLOW GUI.
Updates to to online help.
HydrographExtractor modified to read MT3D Observations file.
Added support for importing concentrations for wells
with MT3D in customized version of MODFLOW GUI.
Version 3.0.7.0 99/06/28 Minor additions to help file. Progressbar PIE now
updates the elapsed and estimated time remaining once each second. The
method used to advance the progress bar has been changed. In the contents
of the help system, the titles of some items have been abbreviated
as a way of working around a bug in the Windows 98 help system.
With the longer titles, Winhelp would crash under Windows 98 but
not Windows 95 or Windows NT 4.0. New capabilities added to
Hydrograph Extractor: (1) reading and writing a file of cell
locations and (2) User can choose activate or deactivate individual
series in the chart. MODFLOW_JoinFiles PIE modified to avoid errors
when attempting to rename files on network drives. Fixed bug
in MODFLOW_CheckVersion PIE function.
Version 3.0.6.0 99/05/28 Modifications to support use of a comma as
a decimal separator.
Version 3.0.5.0 99/05/25 Contour2Data export template corrected. New
fuction added to Edit Contours PIE, Data2Contour, that converts data
points to point contours. Warning message added to GUI when the user
activates MODPATH or ZONEBDGT telling them that they may need
to rerun MODFLOW. Added function to Join Files PIE to facilitate
correct naming of files when the files will be read by DOS.
Added protection for ZONEBDGT stress periods and time steps
that are not entered correctly. Fixed bug in checking that
ZONEBDGT time steps are correct.
Version 3.0.4.0 99/05/20 Changes made to facilitate customization
but no change in functionality.
Version 3.0.3.0 99/05/19 Additional information added to online
help system. Fixed bug in renaming *.s[i] files.
Version 3.0.2.0 99/05/14 Fixed bug that caused porosity grid
parameter not be created correctly in some circumstances. Fixed
bug due to models not recognizing file names with extensions
longer than 3 characters. Extensions of zonebudget zone array
files and specific yied files changed to .a and .y respectively.
PIE functions in progress-bar and join-files PIES were hidden
from the user.
Version 3.0.1.0 99/05/13 Fixed bug in routine to recognize files
saved by previous version of PIE. Activated code to ensure
that options are set properly during export.
Version 3.0 99/04/28 Addition of Help system, STR1, HFB1, FHB1,
MODPATH, and ZONEBDGT; numerous less significant changes
as detailed in the documentation.
Version 2.0 98/07/14 - Addition of MOC3D solute-transport model;
several cosmetic changes.
Version 1.41 97/08/12 - Error corrected that occurred when
considering a confined aquifer and a transient simulation.
Version 1.4 1997/07/23 - Error corrected in export of storativity
for confined aquifers and in export of information for time-
variable and steady stresses. Specific data files can be
exported. Selected geospatial information is checked for errors
upon exporting.
Version 1.3 1997/06/02 - Error corrected in export of vertical
conductance. Problem corrected in postprocessing three-
dimensional surfaces.
Version 1.2 1997/05/13 - Error corrected in handling of "unconfined"
geologic units and in export of wetting threshold for
"unconfined" and "convertible" geologic units.
Version 1.1 1997/04/18 - Error corrected in handling of
"convertible" geologic units. Problem with real-value input
fields corrected. Units corrected in layer menu. Default values
in Misc. Controls and PCG Solver dialog boxes changed.
Version 1.0 1997/03/14 - Initial release.
