Groundwater Flow & Contaminant Transport Modeling Software
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.
Why choose Visual MODFLOW Flex?
Build models faster and more efficiently
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.
Save time and money
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.
Model with confidence
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
Build larger, more complex models
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.
Build credible models
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.
Easily compare multiple models
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.

Powerful Data Visualization
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.
- Visualize all data, including conceptual objects, numerical grids, input data (property zones, boundary condition cells) and output data (calculated heads, pathlines, water table) in state-of-the-art 2D, 3D and multi-view (FlexViewer) displays
- Create cut-away and cross-sectional views that allow you to see inside your model
- Generate 3D animations and movies for reports or the web
- Add isolines, contours, pathlines and color shading to viewers
- Drape raster images (site maps, satellite imagery) over 3D surfaces to show relief
- Optimized OpenGL graphics for enhanced hardware rendering
Efficiently Manage Multiple Models
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.
- Manage multiple model scenarios in a single project
- Easily generate multiple models in parallel for evaluating alternative hydrogeologic interpretations and hypotheses
- Make direct visual and numerical comparisons between different modeling scenarios
- Calculate head differences between multiple model runs, with the same or different grid size
- Compare and analyze multiple modeling scenarios for selecting the best, most realistic model
