Flexible Modeling Approaches Image 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 Build your 3D conceptual model using existing GIS data and wells/boreholes. The grid-independent conceptual model gives you the flexibility to experiment with different grid types and simulators. Cell locations and parameters are automatically calculated for you, reducing the need to define these manually on a cell-based level. From one conceptual model you can easily generate multiple numerical models of different grid types and modeling scenarios, and easily update or modify the model as needed. Learn more » Classical Numerical Modeling Approach Ideal for models with simple geology, basic properties and boundary conditions, the classical approach allows you to start by defining the numerical grid. The grid can then be manually populated with properties and boundary conditions using traditional techniques. Integrated 3D Conceptual and Numerical Groundwater Modeling Image Visual MODFLOW Flex provides a seamless transition from raw data through conceptualization to the numerical model all within a single intuitive modeling environment. 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 Efficiently Manage Multiple Models Image Most modeling projects involve several scenarios/versions, e.g., steady-state vs transient, different properties, inputs, grid types, etc. 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 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, etc) and output data (calculated heads, pathlines) 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 Full GIS Integration Easily construct your grid-independent hydrogeologic conceptual model in minutes using your existing GIS data sets.

Native MODFLOW files Existing Visual MODFLOW Projects (.VMF) 3D Gridded Data 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 finite difference grid/mesh types to accommodate a wide range of applications and geologic conditions (e.g., pinch outs, discontinuities) 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) Unparalleled Power and Performance Take full advantage of 64-bit architecture and multiple core processors, and build bigger models and run simulations significantly faster Available in 64-bit with support for 64-bit engines Multi-core parallel processing for flow engines Benefits Why Visual MODFLOW Flex? Build Models Faster and More Efficiently Never rebuild a model again. Model inputs and grid design can be easily modified and 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. Read more about how the conceptual modeling approach can save you significant time and effort. Since 1995, Visual MODFLOW have been recognized for its intuitive, easy-to-use interface. This has been carried forward in Visual MODFLOW Flex. Groundwater 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. Build Larger, More Complex Models Visual MODFLOW Flex is equipped to handle vast quantities of detailed, high resolution data. With full 64-bit application and engine support, you can now leverage the extra memory available on 64-bit computers and build larger, more complex models. Improve the Credibility of Your Groundwater Models With integrated modeling, model inputs and outputs can be easily visualized with 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. Within a single project, you can easily generate and manage multiple models in parallel for comparing alternative scenarios, grid discretizations or hydrogeologic interpretations. The best model can be selected, thus improving model credibility. Eliminate 3rd Party Software Costs With Integrated Modeling Visual MODFLOW Flex provides both GIS-based 3D conceptual modeling and numerical modeling all in a single integrated software package. 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 views. 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
