Model Viewer: A Program For Three-Dimensional Visualization of Ground-water Model Results

Overview of ModelViewer

Example grid visualization output from ModelViewer.

Model Viewer is a computer program that displays the results of three-dimensional ground-water models. Scalar data (such as hydraulic head or solute concentration) may be displayed as a solid or a set of isosurfaces, using a red-to-blue color spectrum or a custom color scale to represent a range of scalar values. Vector data (such as velocity or specific discharge) are represented by lines oriented to the vector direction and scaled to the vector magnitude. Model Viewer can also display pathlines, cells or nodes that represent model features such as streams and wells, and auxiliary graphical objects such as grid lines and coordinate axes. Users may crop the model grid in different orientations to examine the interior structure of the data. For transient simulations, Model Viewer can animate the time evolution of the simulated quantities. The current version (1.1) of Model Viewer runs on Microsoft Windows 7, Vistas, XP, 2000, NT 4.0, 98, and 95 operating systems, and supports the following models: MODFLOW-2005, MODFLOW-2000, MODFLOW-2000 with the Ground-Water Transport Process, MODFLOW-96, MOC3D (Version 3.5), MODPATH, MT3DMS, SUTRA (Version 2.1), PHAST, and UCODE-2005. Model Viewer is designed to directly read input and output files from these models, thus minimizing the need for additional postprocessing.
