Visual MODFLOW 3D-Builder is the new generation in dynamic conceptual model
building. Featuring a powerful multi-format object/data import tool and tested
to work within the latest version of the Visual MODFLOW modeling environment,
Visual MODFLOW 3D-Builder enables you to build impressive representations of
your groundwater system within a single modeling environment. This means you
save hours when building your numerical model.
Comparison between conceptual and numerical modeling (PDF)
- Build a conceptual model of the
groundwater system, prior to the simulation - The geological
formations, property model, and boundary conditions are all designed outside
the numerical grid; this allows the flexibility to adjust your interpretation
of the groundwater system before applying the numerical grid and converting to
a numerical model.
- Build the model with minimal data
pre-processing required - Working with grid-independent data allows you
to maximize the use of your existing GIS data and incorporate physical geology
and geographic conditions before designing the grid.
- Generate and Simulate regional and
local-scaled models - As the only MODFLOW GUI that supports MODFLOW
2005-LGR, users are now able to design local grids around the area of
interest, directly within the 2D/3D conceptual model environment. Calculated
heads from a regional model can also be used as boundary conditions for
local-scaled models.
- Design the correct model faster -
The grid-independent raw data is left intact and is not constricted by grid
cells when modifying the data or project objective. This allows you to
generate multiple numerical models from the same conceptual model.
- Make changes to the model data and
immediately see results - The conceptual model environment provides
simultaneous 2D/3D views which translates to automatically seeing the results
whenever changes to the data are made.
Data Import
Import raw data from numerous formats and edit data to suit your modeling
requirements. Visual MODFLOW 3D-Builder allows you edit xyz points, shapefiles,
or wells as well as map or draw attributes for points, polylines, and polygons.
You can also view meta-data including statistics and history or edit settings
for changing colors and styles for boundary conditions, wells, points, property
zones, labels, and position. Flexible
Data Operations Conduct several arithmetic or geometric calculations and
easily apply them to the geometry of your data objects or attributes.
Viewing and Editing View your work simultaneously in 2D, 3D or spreadsheet
style and automatically edit your information. Visual MODFLOW 3D-Builder’s
interactive multi-view display allows you to make changes to your data and
display the results in all viewer windows all at once.
Define, Import, and Adjust Surfaces Define surfaces
from well tops, cross sections from Hydro GeoAnalyst, or by interpolating xyz
points. Import surfaces from USGS .DEM, Surfer GRD, ESRI Ascii GRD. Manually
adjust surfaces in 2d/3d or by editing your xyz points. Visual MODFLOW
3D-Builder delivers key features for:
- Loading well tops and creating surface coverage to represent formations
- Loading fence diagrams, cross-sections from Hydro GeoAnalyst, and
interpolating contact points to create surfaces
Structure and Area Layers Define the conceptual model area from a
polygon and vertical horizons from surfaces. Several horizon types accommodate
various geological conditions including pinchouts and discontinuous layers.
Property Zones
Use Shapefiles or CAD polygons/polylines to define property zones. Visual
MODFLOW 3D-Builder supports several methods for defining property zone values,
including: constant values, surfaces (2D Grid), and 3D Gridded Data.
Boundary Conditions Define boundary geometry and attributes with
Shapefiles or CAD polygons/polylines or by using the supported LAK and FHB
packages. Define values for entire zones, or use linear
gradient. Methods for defining property zone values include:
- Constant value
- Surface (2D Grid) (eg river stage from DEM)
- 3D Gridded Data (recharge/evt)
- time schedule
- Shapefile attributes
Support for Horizontal Wells Numerical Grid
Define multiple vertical discretizations including deformed, uniformed and
semi-uniform
- Deformed - easy to design, requires a smaller number of layers
- Uniform (Rectilinear grid) - requires larger number of cells, but fully respects
the finite-difference assumptions
- Semi-Uniform - Top and bottom
layers deform to the horizons; in between, a set of uniformly thick layers
will be generated.
Translation to MODFLOW Once your simulation model
domain is defined, you can easily translate the conceptual objects to the
simulation model grid and create the necessary MODFLOW input files. Visual
MODFLOW 3D-Builder allows you to:
- Define multiple grid discretizations
- Define up to 9 child grids inside a parent grid with the built-in Local Grid refinement tool
- Translate as MODFLOW parameters (for use in PES)
- Select MODFLOW packages to represent boundary conditions (eg, model a
river using MODFLOW RIV package or CHD package)
- Import MODFLOW files into Visual MODFLOW for running the simulation
Preview While finalizing the demo version, we have compile several
flash videos for you to see Visual MODFLOW 3D-Builder's interface and powerful
features. You can either download a .zip file from the demo section or click the
