Visual MODFLOW Flex is more than just a graphical user interface for MODFLOW groundwater simulations. Visual MODFLOW Flex brings together industry-standard codes for groundwater flow and contaminant transport, essential analysis and calibration tools, and stunning 3D visualization capabilities in a single, easy-to-use software environment.
With Visual MODFLOW Flex, groundwater modelers have all the tools required for addressing local to regional-scale water quality, groundwater supply, and source water protection issues.
With integrated 3D conceptual modeling, you will never have to rebuild a model again. Model inputs and grid design can be updated at any point in the modeling process as modeling objectives change, more data are collected and a better understanding of the sub-surface is achieved
Since 1995, Visual MODFLOW has been recognized for its intuitive, easy-to-use interface. With Visual MODFLOW Flex, modeling steps are conveniently presented in an intuitive, workflow-driven graphical user interface, allowing you to see what steps you've completed, your current step and what steps you need to finish to reach your modeling objectives.
Visual MODFLOW Flex provides both GIS-based 3D conceptual modeling and numerical modeling all within a single integrated software environment. This reduces the need to maintain costly 3rd party pre-processing tools and eliminates the error-prone process of transferring data back-and-forth between different software packages and data formats.
The 3D conceptual modeling capabilities allow you to easily interpret and analyze raw GIS data in 2D, 3D and cross-sectional viewers. This provides a visual quality assurance of the data and allows you to gain a solid understanding of the subsurface before designing the numerical model.
Visual MODFLOW Flex is equipped to handle vast quantities of detailed, high resolution data. With 64-bit support, you can leverage the extra memory available on 64-bit computer and simulate large and complex regional-scale groundwater systems.
With integrated modeling, model inputs and outputs can be easily visualized alongside raw GIS field data in 3D. This allows you to establish model credibility by demonstrating how numerical model data (model layers, flow parameters, recharge data) were generated from conceptual data (borehole logs, GIS data). Calculated heads and pathlines can also be displayed alongside conceptual model data to validate assumptions and further demonstrate model credibility.
Visual MODFLOW Flex's unique design permits easy side-by-side comparisons of multiple models allowing you to assess alternative modeling scenarios, grid discretizations and hydrogeologic interpretations.
Advance your technical knowledge and become an expert in no time with a wealth of learning and support resources including step-by-step tutorials, comprehensive user's guide, videos, online training courses.
Visual MODFLOW Flex can be used for an array of groundwater applications.
Visual MODFLOW Flex provides vibrant tools and time-saving workflow options, giving you the ability to efficiently build complex groundwater models. Visually stunning projects are at your fingertips with the new 6.1
Feature | Description |

Easily define zones for subregional water budget calculations by drawing polygon, polylines or points in the desired areas on your numerical model, or by choosing an existing data object, such as a shapefile or DXF layer.
New zones can now be automatically copied to multiple layers and edited directly via CSV file.
The new release introduces support for the Horizontal Flow Barrier (HFB) Package which can be used to simulate barriers to flow such as slurry walls or faults. Wall boundaries are easily assigned using polyline shapes (digitized or existing conceptual model object) to represent the X-Y spatial extents, and horizon objects to represent the vertical extents.
Wall boundaries can be added to multiple layers within your model, and numerical attributes can be edited directly via CSV file. The Wall boundaries on the numerical model can be displayed in 3D view, and 2D views (layer and XS by row or column).
Defining particles for MODPATH simulations has never been easier. In the new release, particles can be assigned by digitizing a circle, or drawing single particles. Particles can be quickly assigned to specific model layers to accommodate multi-layer pumping wells screens.
Particles can be removed from one or more layers. Simply draw a box around the desired area of your numerical model to remove any unwanted particles.
Visual MODFLOW Flex 2014.2 is capable of producing detailed renderings of the water table. In 2D and 3D Viewers, the water table is rendered as a surface with color shading and contours. In cross-section view (row and column), the water table can be viewed as either smooth interpolated line, or as a "discrete" line where MODFLOW cell elevations are honored.
Water table data can be conveniently exported to CSV file for use in post-processing with other software.
Customize the colors and value ranges, and display model properties, boundaries, heads, drawdown, concentrations and the water table exactly how you want them in 2D and 3D Viewers.
Visual MODFLOW Flex 2014.2 gives you complete "back door" access to input files for advanced editing of numerical model data. Input data can be exported to CSV format, edited in Excel or your text editor of choice, and then loaded back into Visual MODFLOW Flex for visualization and processing. If you have existing scripts, these can be hooked up to the CSV file formats for efficient bulk edits of input files.
Model results can now be exported to CSV file format for loading into Excel or your preferred charting software for advanced charting and analysis (Observation vs Calculated Heads, Breakthrough Curves).

Built and designed on the latest in 3D visualization technology, Visual MODFLOW Flex allows you to effectively present and communicate your data to colleagues and stakeholders with impressive visual renderings of your hydrogeologic model.
Most modeling projects involve several scenarios/versions, e.g., steady-state vs transient, different properties, inputs and grid types. Visual MODFLOW Flex allows you to assess uncertainty and improve model credibility through comparisons and analysis of multiple modeling scenarios - all within a single project.
Easily construct your grid-independent hydrogeologic conceptual model in minutes using existing GIS data sets.
Visual MODFLOW Flex provides various grid types from which you can generate your numerical model. Easily experiment with different grid types and choose the one that gives you the best, most stable model.
Take full advantage of 64-bit architecture and multiple core processors, and build bigger models and run simulations significantly faster.
Visual MODFLOW Flex allows you to choose which modeling approach to use for building your groundwater models. Choose the flexible and efficient conceptual modeling approach or the classical modeling approach.
Conceptual Modeling Approach
