Quantitative and Qualitative Information
10
•EnSight can be utilized to not only visualize but also quantify the performance • In this example EnSight calculates the average Cp values on upstream and downstream faces of the radiator package as well as area & mass flow

Viewing CAE Results in 3D Stereo
12
• Active stereoscopic viewing support in all
products since 1997
• Experience with polarized, passive &
active stereo and GeoWall systems
• Provides means to create both active &
passive stereo images and animations
• EnSight is used in Caves by many of our
(bigger) customers

•Complex VR environment: 33 Christie Digital Mirage
projectors IR Motion tracking system
• Runs EnSight DR on a cluster of systems
• User controls the environment by pressing buttons on the wand that are bound to different transformations or user-defined macros

Volume Rendering
19
•Rendering volume elements based on their variable (adjust transparency based on a variable, like velocity) •User control of transfer function relating opacity and variable •First introduced in EnSight in version 9.1 which was released 4 years ago •Particularly useful for simulations of burn cycles, fire, smoke, heating & cooling processes

Linking Various CAE Disciplines: Multi-Physics
23
•With the growth in CAE use, there is also a growing requirement to analyze different physics disciplines together
•Analyse, visualize and communicate different physics in a common, coherent single application & session
•Not only are models themselves becoming larger, but the level of inter- connectivity is growing as well
