Adoption of Agile Development Practices Increases Responsiveness, Quality, and User Access
(download PDF version)
Rutherford, NJ, January 19, 2015 (Intelligent Light) – In support of engineers and managers whose judgment is essential to high-quality, innovative products, Intelligent Light released FieldView Version 15 in October and has now released a new CFD viewer called XDBview. Going beyond the limits of traditional presentation, this new FieldView release gets to the heart of elucidating and uncovering the most important patterns in the behavior of fluids and sharing these insights.
Clarity in CFD Visualization
Potent new colormaps and rapid access to multi-windows layouts help bring clarity and context to complex flow behaviors. FieldView 15 allows users to customize their interface with user-defined colormaps and provides visibility into each colormap from the selection menus. New colormaps with linearly varying luminance provide better insight, print well even in black & white, and remain clear even for those having trouble seeing colors.
“Spectrum style colormaps are commonly used for CFD results visualization but are inherently limited because they use fully saturated colors for their entire scale. This can cause variations in lower gradient regions to be lost”, says Yves-Marie Lefebvre, FieldView Product Chief at Intelligent Light. “To address these limitations, we decided to start promoting the use of scales linearly varying in luminance. FieldView 15 introduces new colormaps with scales that are linearly varying in luminance, providing better representations that are interpreted more easily.”
User response to these changes has been terrific with rapid adoption and broad appeal. Among the new colormaps are schemes that enhance the effectiveness of presentation. Up to 1 in 12 consumers of visual data may be limited in their color perception abilities. The new “achromatic vision” colormaps draw out significant patterns in the data while presenting in a way that is meaningful to those with color blindness and for those with full-spectrum vision.
Agile Software Development Means Increased Responsiveness
This is the first software release created under Intelligent Light’s new agile development process. Designed to be highly responsive to end-users, the process brings selected customers directly into the development process so their input benefits all users of the product. For FieldView 15, several participating users from applications as diverse as Formula 1 to fighter jets have seen their requests implemented in prototypes along the way and are already seeing benefits.
Improved User Experience
FieldView multi-windows allow users to simultaneously compare multiple datasets or multiple views. FieldView 15 adds new Layout RESTART templates for multi-windows that make it easier than ever to layout commonly used views including 3 window formats where two datasets are displayed simultaneously with the numerical comparison between them.
Other user-driven features in FieldView 15:
In Situ CFD a Reality with XDB Extracts Directly from Ultra Scale VisIt Software
Intelligent Light’s commitment to high throughput CFD workflows using XDB extract files supports our customers pursuing in-situ post-processing of very large, unsteady data. In-situ post-processing is performed directly on the solution in memory as it is generated rather than writing traditional solution or post-processing files. Users of the ultra-scalable VisIt code are exporting persistent, compact XDBs directly from VisIt 2.8 during in-situ post-processing and using these with FieldView for high-performance interrogation and visualization. The in-situ approach maximizes throughput and makes results available to analysts as the simulations are developing.
Introducing XDBview – The high-performance, free CFD viewer
The right image or animation will provide a window into fluid behaviors, but interactive exploration by consumers of CFD results increases understanding. The ability of reviewers and collaborators to achieve insights can speed a projects development and improve decision making. XDBview is a free viewer for XDB files that gives colleagues and entire communities the ability to review results of large simulations interactively, with FieldView performance, and without a post processing license.
“XDBview is bringing CFD results to the decision makers: managers, team leaders, CFD customers,” says Lefebvre. “They can finally visualize and compare many large simulation data on their laptops, even when their results are transient.”
“We will use XDBview to send results to non-CFD people who don’t use FieldView. Because we can set up their experience and views, our team members can then manipulate the data to achieve even better understanding.” – CFD Lead, Engineering & Manufacturing
CFD users are embracing the use of XDB files because they solve many problems related to the size and complexity of CFD data which have long made it impractical to move for post-processing and collaboration. XDB files are compact extracts that maintain the full numerical fidelity of your CFD simulation on selected surfaces and streamlines. XDBs are 10x to 1,000x smaller than your CFD dataset and can be easily transferred, shared and archived. Use XDBview to efficiently share the important insights from your results.

VisIt users can now generate FieldView XDB files directly from VisIt scientific visualization software. VisIt is highly scalable, open source visualization software developed by the US Department of Energy. Intelligent Light is working under a DOE SBIR to provide a robust, hardened version of VisIt for engineering applications. VisIt includes libsim which is a powerful tool that can be used in support of in-situ post-processing and visualization. XDB files are generated rather than volume files for interrogation using FieldView. XDBs help accelerate the CFD workflow also allowing researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity. These improved studies can increase accuracy and confidence and lead to new insights.
Researchers and engineers working on leadership class HPC systems use VisIt to work with the large datasets that result. VisIt is built for these ultra-scalable systems, is free of licensing cost at any processor count, and is well suited for work where post-processing takes place as the simulations are run. Writing out FieldView XDB files from Visit in an interactive session or from libsim in-situ provides persistent extract files which can then be used with FieldView software and archived in compact form for later use. Leading users are already using the XDB export capability with in-situ post-processing. FieldView XDB files are a fraction of the size of the original volume data yet retain full numerical fidelity. When used with FieldView they enable both the interactive exploration of unsteady simulation data and the ready transfer of data. FieldView is built for engineering productivity delivering powerful and accessible tools for CFD and supporting investments in high capacity, interactive and automated workflows. This combination bridges the gap between expert users in research domains and engineering experts wishing to use HPC and in-situ post-processing in production environments.
Using XDBs to accelerate the VisIt workflow also allows researchers and engineers to ask more sophisticated questions by running more cases at higher fidelity. These improved studies can increase accuracy and confidence and lead to new insights.
This is a significant milestone in the development and integration of VisIt with the engineering tools in FieldView that users depend on. Intelligent Light’s development was performed largely by Brad Whitlock, a member of our Applied Research Group. Brad is a long-time VisIt developer, formerly working for the Lawrence Livermore National Laboratory (LLNL). Several advanced FieldView users are already using XDBs generated in VisIt. This functionality is delivered in the VisIt 2.8 release for all users and will be supported through normal VisIt support channels. FieldView users will also be supported through their existing Intelligent Light support programs.

Massive CFD Data Handled Quickly Without Compromise – Maximize Your CFD Investment
This real world example uses analysis from the AIAA High Lift Drag Prediction Workshop simulations to show how XDB files enable wholly new levels of productivity for CFD. The work was performed on a remotely located Cray XE6 system and reviewed locally. The improvements in overall throughput can be even higher with VisIt running on the HPC systems and delivering the XDB files directly, without writing out large intermediate files. The work discussed in the paper is was recognized by IDC with their HPC Innovation Excellence Award.

ANSYS® Fluent™ 15 has been released and introduces a new parallel compatible FVUNS export for FieldView. We recommend that this export be used as the default for all ANSYS Fluent datasets as it will result in dramatic performance increases. Performance increases of 5x on 8 cores are typical and this performance boost comes at no cost to FieldView users.
FieldView 14 standard licenses support use of up to 8 processor cores per dataset. For HPC users, additional scalability (32, 64, or unlimited cores) is available at moderate additional cost. Run FieldView on a local system, on-site or cloud-based server, even across virtualized resources all standard and with maximum performance.
The export is available from the FLUENT Text User Interface (TUI). Simple instructions are available from IL support.
