ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey
(USGS) models MODFLOW–2005, MODFLOW-LGR, MODFLOW-LGR2, MODFLOW-NWT, MODFLOW-CFP,
MODPATH, ZONEBUDGET, PHAST, SUTRA and MT3DMS. This software package
provides a GUI for creating the flow and transport input file for PHAST and the
input files for the other models. In
ModelMuse, the spatial data for the model are independent of the grid, and the
temporal data are independent of the stress periods. Being able to input these
data independently allows the user to redefine the spatial and temporal
discretization at will. This report describes the basic concepts required to work
with ModelMuse. These basic concepts include the model grid, data sets, formulas,
objects, the method used to assign values to data sets, and model features.
The ModelMuse main window has a top, front, and side view of the model that can
be used for editing the model, and a 3–D view of the model that can be used to
display properties of the model. The side view is hidden for SUTRA models
ModelMuse has tools to generate and edit the
model grid. It also has a variety of interpolation methods and geographic
functions that can be used to help define the spatial variability of the model.
ModelMuse can be used to execute the models and can also display the results of
all the models except PHAST and ZONEBUDGET. An example of using
ModelMuse with MODFLOW–2005 is included in the report. Several additional examples
are described in the help system for ModelMuse, which can be accessed from the Help
menu.
This report (1) describes modifications to ModelMuse,as described in U.S. Geological
Survey (USGS) Techniques and Methods (TM) 6–A29 (Winston, 2009), to add support for
the Saturated-Unsaturated Transport model (SUTRA) (Voss and Provost, 2002; version
of September 22, 2010) and (2) supplements USGS TM 6–A29. Modifications include
changes to the main ModelMuse window where the model is designed, addition of methods
for generating a finite-element mesh suitable for SUTRA, defining how some functions
should apply when using a finite-element mesh rather than a finite-difference grid
(as originally programmed in ModelMuse), and applying spatial interpolation to angles.
In addition, the report describes ways of handling objects on the front view of the
model and displaying data. A tabulation contains a summary of the new or modified
dialog boxes.
