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.

Simple, easy-to-use

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 indiscretions and hydro-geologic interpretations.
