Integrated Graphs

9

• Integrated graphs into the main viewport or in a separate view •Section through geometry and variable at once•Dynamically updates as you click-n-drag the clip around •Automatic section marker and label


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


Big Data Models

11

Big Models: 15+ Billion Cells and about 12 TB of data


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


LANL Metropolis Center’s 5-sided CAVE

13

•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

Conclusions

26

•EnSight is the leading post processor and visualizing solution for CAE and other types of data •EnSight has had active 3D stereo support for more than 15 years in all our products •Visualizing engineering, scientific and research datasets with EnSight on an active 3D stereo display with head tracking such as the zSpace device can add a lot of valuable information to the user •EnSight can visualize multi-physics datasets that are created by many CAE systems
