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:

  • XDB extracts – reduce data size and speed interpretation by exporting thresholded XDB extracts
  • Users with large models will benefit from a reduced memory footprint for graphics operations.
  • An updated OpenFOAM reader improves both performance and accuracy while reducing read times.
  • New data reader for FLOW-3D version 11 brings users up to speed with FieldView parallel computation and parallel partitioned file read capabilities to dramatically reduce read in and computation times. Every FieldView license supports the use of at least 8 processor cores and FLOW-3D users will now benefit from this capability.

 

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 provides:

  • Ability to review large unsteady datasets interactively at animation speed
  • Agility for on the spot what-if analysis
  • Portability – Work with your data anywhere and share your results with clients, colleagues, and managers.

 

“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.

In-Situ Post-Processing Discussion at NASA Applied Modeling & Simulation

NASA Applied Modeling & Simulation (AMS) Seminar Series to host Intelligent Light speaker on Friday, January 16, 2015. (Series info)

 

In Situ Post-Processing with VisIt, Libsim, and FieldView

Speaker: Brad Whitlock, Applied Research Group, Intelligent Light

The widening gap between compute performance and the ability to store computation results dictates that data analysis and visualization be performed in situ during simulation runs. Saving analysis results and data extracts offers tremendous opportunities for reduction in storage costs while also permitting greater access to data in the temporal domain. Libsim is a library which enables a fully-featured visualization tool, VisIt, to request data as needed from the simulation and apply visualization algorithms in situ with minimal modification to the application code. In this talk, the motivation for in situ processing is presented and the steps to instrument a simulation using Libsim are covered. Instrumenting simulation codes with Libsim opens up new possibilities for higher productivity workflows such as automatic creation of FieldView extract databases (XDBs) which can be visualized efficiently using the post-processing tool FieldView.

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

Helicopter and CarrierDoD’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.

 

Intelligent Light VisIt Services delivered:

  • Rapid deployment of solutions to the problems identified by an expert VisIt developer
  • In-situ extraction via VisIt solves the problems with moving huge files in unsteady computation
  • XDB export in VisIt provides persistent extracts that can be further post-processed and visualized in FieldView
  • Services & support provided by a trusted vendor partner
