Come See us at the Pointwise User Group Meeting

The Pointwise User Group Meeting is coming on September 21-22, 2016 in Fort Worth, Texas and we'll be there. Visit with Joe Oliver, Global Sales Manager to learn how FieldView users are getting more information from their data using the latest in high-productivity post-processing, in situ processing and CFD data management techniques. From grid generation through the delivery of actionable information, the CFD workflow is changing rapidly to keep up with the complexity of high fidelity simulations and the rate at which results can be generated using the compute systems of today.

Mr. Oliver will have a booth and be available to discuss ideas, answer your questions and demonstrate FieldView capabilities. If you will be attending and would like to schedule time with Joe, please Request a meeting.

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.

Come See Us at AIAA Propulsion & Energy

AIAA Propulsion & Energy Forum is coming to Salt Lake City, Utah, July 25-27, 2016 and we'd like to see you there!

Join us in booth #206 to learn how industry leaders like you are benefiting from modern engineered CFD workflows, post-processing and visualization.

Joe Oliver, Global Sales Manager, and Mike Burklund, Applications Engineer, will be on hand to discuss your CFD work and how recent developments by Intelligent Light can help you.

In addition to our participation in the main conference and exhibit, Intelligent Light is also supporting both the Propulsion Aerodynamics Workshop and AIAA's Generation STEM education outreach event (see below).

Attending the conference? We'd like to hear about your interests, goals & challenges. We'd be happy to demonstrate FieldView and answer your questions. See you at Propulsion and Energy!

AIAA PAW03 Workshop
The 3rd AIAA Propulsion Aerodynamics Workshop (PAW03) July 23-24, will focus on assessing the accuracy of CFD in obtaining multi-stream air breathing system performance and flow structure. Intelligent Light is committed to helping engineers efficiently work through vast and varied datasets to produce meaningful results, comparisons and insights. Intelligent Light is a proud sponsor of the PAW03 in support of this community and improved accuracy in CFD.​

We invite workshop participants and all conference attendees to visit our table outside the workshop where Mike Burklund, Applications Engineer, will be on hand to answer questions, explore ideas and demonstrate FieldView. As part of our Custom Engineered Solutions team, Mike has accumulated extensive experience designing and implementing high-throughput workflows for complex CFD.

AIAA Generation STEM
As part of our ongoing support of science and technology education, Intelligent Light will run an aerodynamics station at the AIAA Foundation's second Generation STEM event.  At Generation STEM, middle schoolers from around the Salt Lake City area will take part in a special Science Fair put on by the aerospace community.  It is the only event of its kind where the aerospace industryis interacting directly with students. The inaugural Generation Stem event in 2015 was a great success and we look forward to more success this year!

FieldView integral to Hands on FrontFlow/blue Training

On July 1st, 2016, the Center for Research on Innovative Simulation Software at the University of Tokyo will host the seminar; "7th Practical hands on training on FrontFlow/blue" in Kobe, Japan.

The FOCUS Foundation for Computational Science and our partner VINAS, will co-host the seminar in corporation with Mizuho Information & Research Institute.

Prof. Chisachi Kato, Institute of Industrial Science, The University of Tokyo

The seminar will use the example case: "Acoustic noise optimization of the fan". As an attendee you will experience an entire CFD workflow from mesh generation, running the simulation, post-processing and optimization. FieldView will be employed as the post-processing tool providing an opportunity to learn how to use FieldView through valuable hands-on experience. If you are considering FieldView and wanted to have a chance to touch it, this will be a great opportunity. The seminar is free. You will be able to experience not only FieldView but also Pointwise software for mesh generation, the open source CFD solver FrontFlow/blue and optimization software. At the end of the seminar, Prof. Chisachi Kato, the development leader of FrontFlow/blue, will make the presentation.
