EnSight Animation


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


Quantitative and Qualitative Information
•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

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

Viewing CAE Results in 3D Stereo
• 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
• 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

Texture Mapping – Vortex Control for Boeing C-17 Aircraft


Texture Mapped In-Cylinder HCCI Model


Ray Tracing – Photo Realistic Output


Volume Rendering
•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

Volume Rendering Example in EnSight 10


Not Only CFD: also FEA, MBD, DEM, CAD, MBD etc

Linking Various CAE Disciplines: Multi-Physics
•Not only are models themselves becoming larger, but the level of interconnectivity is growing as well
•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

Conclusions
•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
