Comprehensive Groundwater Modeling With Visual MODFLOW Flex you have a comprehensive set of tools necessary for addressing water quality, groundwater supply, and source water protection initiatives, including: MODFLOW-2000, 2005 The world standard for groundwater flow modeling MODFLOW-USG A finite volume version of MODFLOW that uses unstructured grids. Learn more 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 View all supported flow engines, transport engines and MODFLOW packages. 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 Full GIS Integration Easily construct your grid-independent hydrogeologic conceptual model in minutes using existing GIS data sets. 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 View all supported files types Flexible Grid Options 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. 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)
