PowerVIZ Overview
Easy and Versatile Analysis of PowerFLOW Results
PowerVIZ is the high-performance visualization and analysis application used for processing simulation results from PowerFLOW and spectral analysis results from PowerSPECTRUM. It provides a wide variety of tools to perform detailed analyses, a fast, intuitive, and interactive user interface, and the ability to quickly process even the largest data sets. Different visualization techniques can easily be combined within the same image to explore your simulation data as never before . PowerVIZ can also be scripted, making even the most detailed analysis a push-button operation.

Features/Benefits/Highlights:
- Super High Performance: Interactive and intuitive handling of large data sets
- Scriptable: Create scripts to automate standard visualization and analysis practices, or use standard scripts provided by other users
- Quantitative and Qualitative: Compute specific, meaningful quantities such as net force and mass flux, or show detailed images to illustrate complex flow features
- Flexible: Dozens of analysis techniques for nearly any need; powerful, simple mechanism for deriving any desired quantity from existing quantities

Visualization Techniques for Surface Data:
- Surface contours
- Force development graphs: integrated force along a user-defined line segment
- Torque calculations; simple front/rear axle lift coefficient calculation
- Color coding of surface geometry by surface data
- Surface particle tracing (streamlines)
- 2D graphs of surface scalar values

Scripting:
PowerVIZ supports full scripting of all features via extensions to the Python language. Scripts can be recorded as the user performs actions in the GUI. Scripts and used to:
- Automate standard analysis sequences
- Recreate a standard analysis setup
- Generate animations & movies
