Visual MODFLOW Flex

• MODFLOW-2000, 2005, NWT – The world standard for groundwater flow modeling
• MODFLOW-USG – A finite volume version of MODFLOW that uses unstructured grids.
• MODFLOW-LGR – Shared-node local grid refinement (LGR) for regional-local scale simulations
• MT3DMS – The standard package for multi-species contaminant transport simulations
• MODPATH – The standard package for forward and reverse particle tracking
• Zone Budget – A package for sub-regional water budget calculations
• PEST v.12.3 – Automated calibration and sensitivity analysis with support for pilot points

• Define complex geology and model layers using borehole log data and cross-sections
• Interpret GIS data to define hydrogeologic properties and boundaries independent of the grid
• Run, analyze, and validate model results with raw data in 2D, 3D, and cross-section views
• Easily create multiple conceptualizations; generate numerous grids and model scenarios in parallel all in a single project
• Assess uncertainty though comparing heads from multiple model runs in 2D, 3D or chart views

• Quick and easy data importing of all common file types and formats
• Automatic coordinate system and units conversion on import
• Automatic data validation and intelligent error checking on import
• Define model boundaries, property zones, boundary conditions and attributes from imported GIS data

• Choose from various structured and unstructured grid types to accommodate a wide range of applications and geologic conditions (e.g., pinch outs, discontinuities)
• Improve simulation accuracy, reduce runtimes and increase model stability with unstructured grid types (MODFLOW-USG)
• Easily generate multiple grids within the same project and compare side-by-side in 2D or 3D
• Perform grid refinement around areas of interest
• Create faster more stable models with nested child grids that contain local horizontal and vertical refinement (MODFLOW-LGR)

• 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

Hardware Requirements

• Operating Systems – Windows 10 Pro or Enterprise
• Windows 8.1 Pro or Enterprise, Windows 7 Professional, Enterprise or Ultimate
• Processor  – 32-bit or 64-bit
• Hard Disk – 500 MB
• RAM – 2 GB (4 GB or more recommended)
• Networking Hardware – Network Card (required for soft key licensing)

Software Requirements

• Microsoft .NET Framework 4.0
• Microsoft Office (2000 or later). If you do not have Office, you must install the Microsoft Access Database Engine.t.

If you intend to work with large models (est. > 500,000 nodes), it is recommended that you use 64-bit version of Visual MODFLOW Flex, and increase your RAM (recommended 10 GB or more).
