Features Both its software features and the range of physical processes covered make FEFLOW unique among today's groundwater modeling software. No matter whether you need to quickly confirm rule-of-thumb assumptions for everyday engineering decisions or you apply large complex models as a basis for multi-million Euro or Dollar investments with possibly detrimental environmental impacts - FEFLOW provides the exactly right proportion between ease of use and necessary complexity of the approach. Analysis Analysis and postprocessing features are crucial for calibration and results evaluation. FEFLOW provides easy-to-use tools and visualization options: * Diagram windows for observation wells * Export of model parameters and results as values, vector plots and images * Budgeting of water, solute, and heat flows for the model domain or parts of it * Particle tracking with isochrone markers o Steady-state or transient o 2D or 3D view Visualization Up-to-date visualization tools - including animations - support the presentation of modeling results to the client and the public. On the other hand, for complex large models, visual perception of all aspects of the model is also strictly required from the point of view of the modeler while editing input data and analyzing simulation results. FEFLOW provides: * Bird's eye and cross-sectional views * 3D view * 2D and 3D map support * Arbitrary combination of model parameters, maps, and visualization styles in each view * Clipping and carving * Isolines, filled contours, continuous plots, vectors. isosurfaces, streamlines, pathlines, ... * Image export in different formats and with customizable resolution * Animation and video export * Live visualization of current results during simulation The free software FEFLOW Viewer provides all visualization and postprocessing capabilities without requiring a license for FEFLOW.
