EnSight Speaker’s Bureau
Back when I worked at NASA we had a speaker’s bureau, they probably still do, anyway you could sign up and then if a school or the Rotarians wanted an astronaut to come visit their class and explain how to go potty in orbit (#1 question) NASA could send a lowly engineer instead and keep the astronaut busy training for their next mission.
Here at CEI we don’t have such a huge demand for speakers. But from time to time we try to think about planning our next user meeting. And of course we’ll always talk about the latest release and probably about the one planned for after that. But the best talks are aways from the EnSight users, because you guys are doing the cool things with jet cars, unmanned vehicles, world’s largest dump trucks, and new ways to peer into the human heart with MRI.
So we’re asking, no begging you to consider registering as a potential user meeting speaker. We made an easy form. Filling it out only expresses interest – not commitment. And sometimes we even have budget to help or provide travel expenses. Last year Darren Grove from Boeing spoke in Tokyo at our Japanese EnSight Forum on the work on the North American Eagle.
Please register if you like to travel and you can talk about your work to other engineers.
Support Corner – Calculator Performance Tip
Here’s an interesting calculator problem,
You know that
var{5} is the value of the variable at timestep 5
and
var{0} is the value of the variable at timestep 0.
If you want to know the difference between the two,
you can put the following expression in the calculator.
var{5} – var{0]
but, for models of any size, it is so slow it appears to hang.
Why?
If you include a reference to a variable from two or more different
timesteps, the calculator will change back and forth between timesteps element
by element or node by node and take a considerable amount of time. If you
need to do a calculation with two different timesteps, assign each of the
timesteps to a temporary variable, then use the temporary variables in your
calculation.
For example,
var{5} – var{0}
is prone to drastic slowdown in EnSight. Whereas
temp5 = var{5}
temp0 = var{0}
temp5-temp0
will run much faster.
This is documented in Knowledge Base under Calculator Variable Problems, and now in ch 7 of the User Manual.

You can right-click and Delete a session file. More.
Multi-core Unstructured Volume Rendering. Threading of the structured volume rendering can significantly improve the sampling from the unstructured data.
Offset Parts. Offset parts of an elevated surface can now use surface normals or the user can specify the normal to be used.
Timestep Read Ahead Thread. In some cases a performance boost for EnSight can be obtained by assigning a thread to touch files belonging to the next time step in anticipation that they will be used next. It is not enabled by default, you have to turn this on by setting an environment variable or using a test: command. (More: How To Manual >; Introduction >; Use Environment Variables).
ENSIGHT_PRECACHE_ENABLE [0/1] 0 means disabled, 1 means enabled.
Part Constant Query user-defined tool. This useful tool has been enhanced to include support for RTZ clips. User Tools >; Analyze >; Part Constant Query. More.
CEISHELL. EnSight’s launch technology for parallel and distributed environments adds support for multi-hop VPN; this provides communications between EnSight components operating on computers separated by multiple network links. CEIShell Launcher is a GUI-based utility for launching CEIShell networks, querying their status, and launching EnSight on top of the CEIShell network. The EnSight Client now includes a CEIShell log window for displaying CEIShell messages along with output from EnSight components launched via CEIShell.
Large part support. EnSight can now handle a single part with more
than 2Billion nodes or elements.
EnSight DR. Both multi panel and parallel composite capability is now active.
Create Analytical Rigid Surfaces from ABAQUS ODB data. A user-defined tool has been created by CEI to read the 1D parts in the ABAQUS ODB data and create analytical surfaces in EnSight. User Tools >; Visualize >; Create ARS. More.

Prometheus Engineers Improved Fire
“Communicating the results of CFD analysis is critical to a successful project and our business. It can be difficult to explain to someone not familiar with CFD what they are looking at. The ease with which we can change views, compare different cases side-by-side, and create animations in EnSight allows us to provide the necessary perspective to our customers for a more successful presentation. Furthermore, the ability to use macros to format the data is invaluable for reviewing results quickly and efficiently. ” Emmanuella Sotiropoulou, Vice President, Engineering Prometheus Applied Technologies, LLC
EnSight 10.0.1b Release Notes
New or Major Capabilities Added
New NASTRAN OP2 (beta) Reader. The NASTRAN OP2 reader reads some OP2 files that the existing reader was not able to read. Both the existing and this new alternative NASTRAN readers remain available. We would appreciate feedback when customers have tried them both on the same dataset.
New GMV Reader. GMV is the format used by ConvergeCFD and Barracuda and sometimes KIVA. This is just an Alpha reader we are releasing to get customer participation in the pre-release testing phase.
Checkpoints. Checkpoints are automatically created session files useful for if/when EnSight crashes and you want to return to your work. No need to waste time making session files manually or recreating your work in EnSight manually. To install checkpoints go to: User Tools > Utilities. You set how often checkpoints are saved and how many you want to be saved before the old ones are deleted. Notice also that there is a manual checkpoints utility you can also put in your Main toolbar for manual checkpoints. Access Checkpoints in the Welcome Window, Window > Welcome To.
Stereo viewing control panel in User Tools. Controls the eye separation values for stereo viewing.
The command language manual is back, but is not accessible via the GUI. We do include the file now.
Improved multi-value input in the transformation editor (e.g. single entry of vectors, etc) and other locations.
International Fonts. We now support ‘font linking’. This allows for improved display of font glyphs that are not available in the current font. The classic example is a variable name with Japanese text in it displaying as ‘squares’ using the default annotation font, ‘Arial’. In 10.0.1(b) on a Japanese Windows system the text should display properly.
There were some changes that improve startup performance in specific environmental situations (e.g. large numbers of fonts and some network drive cases).
‘dconfig’ displays now supported. This applies to multiple displays connected from a single graphics card. (No Distributed Rendering (DR) support yet in v10.0).
EnVe includes some additional tools for stereo .evo manipulation: extraction of channels, swapping of channels, creation of ‘side-by-side’ style stereo framing used by the nVidia stereo movie viewer and Youtube.
