"When you're a challenger, you have to think differently...Golf sometimes has been slow to adapt to new ideas, so anytime you're in the position of being a challenger, you have to be willing to break the mold."

Michael Vrska, Director of Innovation at Wilson Golf

Wilson Labs uses Altair's Virtual Wind Tunnel software to test aerodynamic performance empowering them to create revolutionary new products faster. The CFD suite includes AcuFieldView, a version of FieldView for Altair CFD users designed to support engineering driven organizations like Wilson Labs.

See FieldView in action as Wilson Labs explains how they use CFD to design sporting goods, and in particular golf clubs, as featured on the 7-part Golf Channel series DRIVER vs. DRIVER.

It is "...about the expertise of the team of engineers at Wilson Labs...a good idea for a golf club is merely a start. Its execution to a finished product requires technological horsepower."

    Data Handling and Visualization for Large CFD Simulations

    Hear it for yourself!  

    LIVE Webinar

    Register now!

    Large scale CFD run on HPC systems generate huge volumes of results requiring a workflow that allows users to manage the large data and extract useful information efficiently. Workflows that do not keep pace with the rate of simulation prevent people from making the most of their simulations. The negative outcomes can include not sharing data effectively or perhaps even avoiding the use of HPC resources to begin with.

    We've made it simple to use the best resources available for your CFD. We'll show you how we are helping our customers achieve the promise of HPC for large CFD by reducing the data bottleneck and lowering costs. Cray and Intelligent Light invite you to join this live discussion and learn how some of the most productive CFD users in the world are working with their large data.

    We'll also discuss an industry collaboration aimed at improving the quality of CFD simulation of the physics of helicopter flight. The AIAA Hover Prediction Workshop uses data from multiple organizations submitting varied solutions for a helicopter in hover. The results are brought together on an shared HPC resource where standardized, automated post-processing is performed. Results are directly compared, reports are generated and extracts are delivered that can be shared, explored interactively and archived.

    ISC Workshop on In Situ Visualization

    Time step from the evolution of temporal mixing layer from initial to vortex breakdown. AVF/Leslie simulation performed using up to 131,072 cores on DOE's TITAN supercomputer. In situ processing using VisIt software delivered the images related plots and XDB files for the researchers. Time step 150,000 out of 200,000.

    This summer I presented a talk called In Situ Production of Extract Databases for Visualization to the Workshop on In Situ Visualization at the ISC Conference held in Frankfurt, Germany. In situ takes workflows that have been created post hoc and executes them directly on simulation data in memory while the simulation is running. The workshop was attended by visualization experts mainly from Europe and the US and talks focused on using in situ software to address the challenges of being able to save sufficient simulation data on supercomputers.

    Hank Childs from the University of Oregon, a prominent visualization expert, gave a keynote address emphasizing the importance of in situ against the backdrop of upcoming exascale machines with their diminishing memory per core and lower relative I/O bandwidth compared to today's machines. Jens Henrik Goebbert from Aachen University presented an abstraction library that simplifies in situ integration with multiple in situ infrastructures, including Libsim. Roberto Sisneros from NCSA presented work on a parameter study highlighting the importance of providing good default application settings and showed that performance for VisIt's streamline plot could be enhanced by simply improving the default settings.

    My talk summarized Intelligent Light's in situ efforts with VisIt, Libsim and our extract database files (XDB). Specifically, we instrument a simulation for in situ using Libsim, which brings VisIt's capabilities into the simulation. We developed a library that efficiently writes the FieldView XDB files and added it as an export option to VisIt. The simulation uses VisIt to create surface geometry extracts, typically without making any copies of simulation data, and exports the extract as a FieldView XDB file. Tight coupling of simulation to visualization and analysis provides opportunities to perform data reductions that result in smaller, concentrated, more useful results being written out more frequently, avoiding the costs of writing and later reading large volume datasets.

    ​I presented results from running the AVF-LESLIE combustion code on the Titan machine at Oak Ridge National Laboratory using an in situ rendering workflow and our extract database workflow. For the rendering workflow we were able to run the code up to 131K cores and render images of slices and isosurfaces from the simulation every 5 time steps to produce a visualization of a turbulent mixing layer of 2 fluids. In another of our experiments, we extracted surface-based results, saving the geometry plus field data to our XDB format for later post-processing within FieldView. We saved XDB extracts from every 5th time step, taking around 2% of the simulation runtime. Each XDB file was over 200x smaller than the corresponding volume data file. We wrote 20 XDB files for every volume output file and the combined size of 20 XDB files was still 10x smaller than a single volume output file.

    LIVE Webinar Thursday May 5, 2016, 2:00 PM ESTWatch the recording now.

    Please join Steve Legensky, Founder and General Manager of Intelligent Light, for a live web event "Speed Up Production CFD Workflows with Extract Post-Processing"

    This event is designed to help you achieve greater throughput of:

    • Standardized plots and reports
    • Unsteady results
    • Remote HPC computing
    • Large CFD data

    ​Parallel computing has enabled CFD practitioners to create far more data than can be stored or accessed for post-processing and analysis, making it difficult for engineers and researchers to gain understanding via visualization, exploration and collaboration.

    Mr. Legensky will present:

    • Techniques and customer examples that show how extract-based methods have graduated from the research realm to the production environment
    • Our recent success applying in situ techniques to production level workflows that scale from hundreds of cores to over 130,000 cores
    • The new HPC FieldView software that combines the power of open-source VisIt software with the ease-of-use and productivity of FieldView
    Steve will answer questions after the presentation in a live Q&A.
