Predictive Analytics SoftWare (PASW) Statistics 18 (formerly SPSS Statistics) puts the power of advanced statistical analysis in your hands. Whether you are a beginner or an experienced statistician, its comprehensive set of tools will meet your needs.

The Watershed Modeling System (WMS) is a comprehensive graphical modeling environment for all phases of watershed hydrology and hydraulics. WMS includes powerful tools to automate modeling processes such as automated basin delineation, geometric parameter calculations, GIS overlay computations (CN, rainfall depth, roughness coefficients, etc.), cross-section extraction from terrain data, and more! WMS supports hydrologic modeling with HEC-1, HEC-HMS, TR-20, TR-55, Rational Method, NFF, MODRAT, OC Rational, HSPF, xpswmm, and EPA-SWMM. Hydraulic models supported include HEC-RAS, xpswmm, EPA-SWMM, SMPDBK, and CE-QUAL-W2. 2D distributed hydrologic models (including channel hydraulics and groundwater interaction) can now be created with GSSHA, developed by the US Army Corps of Engineers. All modeling is handled by a GIS-based data processing framework that makes the task of watershed modeling and mapping easier than ever before.

The Groundwater Modeling System (GMS) is a comprehensive groundwater modeling environment. GMS provides GIS based graphical preprocessing tools to automate and streamline the modeling process. GMS interfaces with MODFLOW and several other standard groundwater models, and provides advanced graphical features for viewing and calibrating model results. With thousands of users at U.S. and foreign government agencies, private firms, and universities, GMS has proven to be the modeling system of choice for groundwater professionals.

GMS Applications
GMS provides tools for every phase of a groundwater simulation including site characterization, model development, calibration, post-processing, and visualization. GMS supports a number of finite-difference and finite-element models in 2D and 3D including MODAEM, MODFLOW 2000, MODPATH, MT3DMS, RT3D, SEAM3D, FEMWATER, PEST, SEEP2D and UTEXAS. GMS can be used for a number of modeling applications including site visualization, aquifer resource studies, well field management and permitting, site contamination evaluation and cleanup, natural attenuation and bioremediation, as well as seepage and slope stability.

GMS Features
The Groundwater Modeling System (GMS) is a comprehensive graphical user environment for performing groundwater simulations. GMS consists of a graphical user interface (the GMS program) and a number of analysis codes (MODFLOW, MT3DMS, etc.). GMS is used as a preprocessor to graphically create numerical models, and as a post processor to import and visualize model results. GMS uses a Conceptual Modeling Approach to create and manage numerical models using GIS based s. Other powerful GMS features include 3D Model Conceptualization, Site Visualization, Advanced Geostatistics, Automated Calibration, and Stochastic Modeling. GMS also has advanced tools for Data Import, Data Export and Data Visualization and Animation.

GMS Modules
The interface for GMS is divided into eleven modules. A module is provided for each of the basic data types supported by GMS. As you switch from one module to another module, the Dynamic Tool Palette and the Menus change. This allows you to focus only on the tools and commands related to the data type you wish to use in the modeling process. Switching from one module to another can be done instantaneously to facilitate the simultaneous use of several data types when necessary.

GMS Models
Numerical models are programs that are separate from GMS that are used to run a detailed mathematical analysis representing the groundwater flow or other physical behavior. GMS supports several types of models including analytical element, finite difference and finite element models. GMS supports the numerical models as a pre- and post-processor. The model elements and parameters are defined in GMS and saved to a set of standard input files. These files are then read by the model when the model is executed when launched from the GMS menu. Once the analysis is complete in the numerical model, the results are read into GMS for review and display (postprocessing). GMS also has the option of using a "model wrapper" to run the model and display real-time results during the model simulation. Numerical models to the left are currently supported in GMS. Each model is included with the GMS installation (model executable files and documentation) and is fully linked with the GMS software.

Maxwell is the leading electromagnetic field simulation software used for the design and analysis of 3D/2D structures, such as motors, actuators, transformers and other electric and electromechanical devices common to automotive, military/aerospace, and industrial systems. Based on the Finite Element Method (FEM), Maxwell accurately solves static, frequency-domain and time-varying electromagnetic and electric fields. Maxwell v12 improves engineering productivity, reduces development time, and assures first-pass design success. New Distributed Solve and multi-processing enhancements allow users to solve very complex, electromagnetically large geometry faster and to expand beyond what they ever thought possible with simulation technology. Additionally, Maxwell v12 includes new automation features, user-interface refinement, and data linking capability, making it easy to design, simulate, and validate complex, high-performance electromechanical and electromagnetic devices.

The Surface Water Modeling System (SMS) is a comprehensive graphic user environment for one- and two-dimensional surface water models. SMS provides GIS based graphical preprocessing tools to automate mesh generation and modeling process, and advanced post-processing visualization tools for results review and presentation. SMS included a range of hydraulic and coastal models for applications including river flow analysis, contaminant and sediment transport, rural and urban flooding, estuary and inlet modeling, coastal circulation and wave modeling.
