In-Situ Solver Integration using VisIt on the CREATE/AV Program

by Roger Rintala | January 5, 2015 8:45 am

Helicopter and Carrier[1]DoD’s CREATE/AV Kestrel team has demonstrated in-situ post-processing using DOE’s VisIt code with FieldView XDB export.

 

The US Air Force, Navy and Army make extensive use of large scale simulation in their research, design and procurement activities.  Over the past five years the DoD CREATE program has sought to develop and deploy new simulation technologies to assist in the procurement process.

 

As part of a ship-airwake program, engineers at the US Navy’s NAVAIR were tasked with simulating a helicopter flying towards a ship. This was a particularly challenging case due to the sheer size of the results files computed on an HPC resource.  Handling the files was an impediment to effective understanding.  With support from Intelligent Light’s VisIt Services, the team now has the ability to use their solver with open-source VisIt LibSim software module to perform in-situ post-processing and export XDB files.

 

Intelligent Light also provided support and enhanced VisIt to make it suitable for the complex mesh topologies common in Kestrel. The VisIt 2.8.0 release has many of these enhancements and the XDB export capability.

Corvid uses IL VisIt Services to Customize & Improve VisIt

by Roger Rintala | January 5, 2015 8:15 am

Crew Protection[1]When working with large scale, unsteady, multiphysics simulations, Corvid Technologies makes extensive use of VisIt for post-processing and visualization of results.  VisIt helps them exploit HPC to present powerful, illuminating images and animations that share the knowledge gained through engineering simulation with clients.

 

Corvid Technologies turned to Intelligent Light when it became clear that some problems with their solver interface were inherent in the open-source VisIt code.  They needed results and to keep their staff working on other projects where their expertise was most valuable.

Revolutionizing Innovation with On-Demand HPC

by Roger Rintala | January 5, 2015 8:00 am

Many of our customers depend on HPC every day. Our direct involvement with customers working at the leading edge of HPC driven engineering is making people vastly more productive as they harness the power of HPC.

 

Successful example of cloud-based HPC for CFD use. Presented by Intelligent Light's Steve Legensky.[1]

Successful examples of cloud-based HPC for CFD use. Data management and workflow engineering are important to the success of cloud-based CFD. Presented by Steve Legensky, General Manager and Founder, Intelligent Light.

Steve Legensky, our General Manager and Founder,  was recently invited to provide examples and successful strategies for cloud-based HPC.  The talks were delivered for the SC14 HPC Impact Showcase[2] and the  HPC User Forum[3] in Seattle.

 

Recognizing that CFD Solver Codes are often well suited to running in the cloud, CFD remains problematic for many because the results files can be very large and there can be many.  Effective analysis of these files essential to the CFD workflow and is the way users gain understanding.  Overcoming the constraints requires both data management and workflow engineering to deliver on the promise of on-demand HPC for CFD.

Leading Edge CFD Post-Processing in the Automotive Industry

by Yves-Marie Lefebvre | October 8, 2014 9:00 pm

Intelligent Light delivered a keynote presentation at the VINAS User Conference[1] in Shinagawa, Japan.

 

How the Automotive Industry is Pushing the Limits of CFD Post-Processing with FieldView[2]

CFD Engineers working in the automotive industry are being asked to simulate increasingly complex systems and phenomena, while having to deal with strong time and cost constraints. This is probably the reason why an increasing number of them are switching to FieldView, after trying other commercial or open source post-processors. In this presentation, we’ll review three automotive industrial examples, covering areas as different as engine thermal validation, external aero and internal combustion, which used the same technology (FieldView’s automation, high performance graphics and data extracts capabilities) but applied in different ways, thanks to the help of Intelligent Light’s Services Team. What these three companies had in common was the need to do more with the same hardware, whether that’s getting their post-processing results faster or being able to interact with large transient results in a way it had never been done before.

SAE Supermileage: Concordia Team Completes Testing

by Roger Rintala | June 2, 2014 12:39 pm

Competition Results Update!

Concordia U - SAE Supermileage Team 2014[1]Congratulations to the Concordia University Team on their win of the 2014 Endurance Award for reliability on the track.  With 208 design points and 448 MPG, the team achieved their first top 10 finish in their 18 year history in the SAE Supermileage Competition.

 

FieldView has become a core element of their workflow and will help the team continue to develop their capabilities every year as team members change over time.  CFD driven improvements to the engine are already being planned for 2015 and FieldView will be used for their new internal combustion studies.

The use of basic automation including FieldView RESTART files saved Mr. Eminanlou days to weeks as he worked with successive design cases.

Body Design Lead Mehran Eminanlou has performed CFD analysis for the team contributing to the engineering knowledge and resulting designs for both external aerodynamics and evaluation of the fuel inlet.  FieldView has been used to quickly analyze results from Ansys Fluent for multiple design iterations and on-track wind conditions. FieldView provided the capabilities to evaluate results and create high-quality, informative images, animations, and plots for presentation at design reviews.  The speed of FieldView and ability to work efficiently to analyze and compare multiple cases proved to be essential to the project.  Moreover, the functionality was accessible without the need to spend lots of time learning how to utilize the required features.  The use of basic automation including FieldView RESTART files saved Mr. Eminanlou days to weeks as he worked with successive design cases.

 

Good luck in Detroit gentlemen!
