Dr Ben Evans, Bloodhound SSC’s Computational Fluid Dynamics (CFD) Engineer.
Using high performance computers is the only way, really, you can do realistic flow simulations for a vehicle as complex as this,” said Dr Ben Evans, Bloodhound SSC’s Computational Fluid Dynamics (CFD) Engineer. There are lots of things we need to understand about the aerodynamics of the vehicle to make sure that it’s safe; we need to understand where the loads are distributed across the vehicle, we need to understand if we’ve got the drag (the resistive force of the air that will be pushing on the car) as low as it can be so that our engines can propel us to the speeds we are going for; and to do the modelling to understand all of that requires some incredibly complex calculations to process massive amounts of data. HPC Wales has been invaluable to us, simply because of the size of the machine and the amount of resource that we’ve got access to. It allows us to run simulations much quicker than we’ve ever been able to do before, which has allowed us to run more simulations than we’ve ever been able to do before. This has allowed us to understand this vehicle better than really we’d ever hoped to be able to do at this stage of the project.

Should CFD be an Exact Science?
Search Results for: cfd
Over at the IMAGINiT CFD Blog, Ryan Stamm writes that while Computational Fluid Dynamics is not an exact science, it is good engineering.
I’ve been asked to carry out results data to 3 or 4 decimal places! Really? Do results showing 4.015 psi drive product development in a different direction than 4 psi? If so, you don’t need CFD simulation, you need a professor and enough capital to embark on a 6 month research project. Don’t get me wrong, CFD analysis can be exact! However it requires a high degree of scrutiny and more time to capture every minuscule detail. I come across many engineers who feel the need to include every detail is required to derive any value from simulation. This cannot be further from the truth. CFD can be exact but CFD does not have to be exact to drive product development decisions.

D3 Applied Technologies selects CIARA as Official Technology Provider
Search Results for: cfd
Today D3 Applied Technologies announced that the company has selected CIARA Technologies of Montreal as their primary technology systems provider. D3 Applied Technologies will make use of the CIARA products for doing high fidelity computational fluid dynamics simulations in order to enable engineers to predict the performance and optimize their products providing as well a greater insight into previously hard to study areas.
The computational fluid dynamics, CFD, simulations we run at D3 are very high resolution and therefore extremely demanding,” said Gonzalo Redondo, CEO of D3 Applied Technologies. “Thanks to CIARA, the time required to converge them has been reduced by a factor of four by making use of our NEXXUS C cluster featuring InfiniBand and SSD disks. Thanks to the integrated liquid cooling there is no need for external air conditioning units that would increase power demand significantly. It is still fascinating looking at it knowing this piece of hardware has become our best wind tunnel.”
Redondo founded D3 Applied Technologies in 2012. With know-how acquired as design members of America’s Cup and Volvo Ocean Race design teams, the company already has a well-established portfolio in the maritime industry. Read the Full Story.

Stanford Researchers Conduct First-ever Million-core CFD Run on Sequoia Super
Search Results for: cfd
Andrew Myers writes that Stanford researchers using the Sequoia IBM Bluegene/Q system at LLNL have set a new record, harnessing a million compute cores to model supersonic jet noise.
These runs represent at least an order-of-magnitude increase in computational power over the largest simulations performed at the Center for Turbulence Research previously,” said Joseph Nichols, a research associate in the center. “The implications for predictive science are mind-boggling.” Sequoia once topped list of the world’s most powerful supercomputers, boasting 1,572,864 compute cores and 1.6 petabytes of memory connected by a high-speed five-dimensional torus interconnect. Because of Sequoia’s impressive numbers of cores, Nichols was able to show for the first time that million-core fluid dynamics simulations are possible—and also to contribute to research aimed at designing quieter aircraft engines.”
In addition to jet noise simulations, Stanford researchers in the DoE-sponsored Predictive Science Academic Alliance Program are using the CharLES code to investigate advanced-concept scramjet propulsion systems used in hypersonic flight and to simulate the turbulent flow over an entire airplane wing.

CFD Gives Athletes a Competitive Edge
Search Results for: cfd
Over at Wired, Madhumita Venkataramanan writes that mechanical engineers at Sheffield Hallam University are using full CFD modeling to help triathletes be more competitive.
To build this visualisation, known as a computational fluid-dynamics model, Ranchordas’s body shape and geometry was captured with a robotic scanner. Next, his contours were put into a virtual wind-tunnel, where scientists played around with values such as wind velocity and direction. The model can then predict how air flows around his body.

Intel’s Voyager Award Goes to Flow Science at SC12
Search Results for: cfd
This week at SC12, Flow Science, developers of FLOW-3D, a highly-accurate computational fluid dynamics (CFD) package, has won the Intel®Cluster Ready Voyager Award for the second year in a row. The Voyager Awards recognize those organizations that have contributed to Intel® Cluster Ready advancement and total available market growth and helped penetrate the much sought after but elusive “missing middle” for customers moving to cluster-based solutions.
Working with the Intel support team, we were able exceed what had been a previous scaling limit of 32 cores,” said Anup Gokarn, Senior FLOW- 3D/MP Developer. “After enabling our software for distributed memory parallelism, we were able to run on more than 32 cores of Intel’s latest processor architecture and find out how the software performed.”
CFD lies at the core of most industrial design cycles in hydraulics, aerospace, casting, microfluidics and other engineering applications. As hardware architectures evolve, engineers are constantly trying to solve large complex simulations with reduced runtimes in order to optimize their design cycles. Flow Science developers have collaborated with Intel technical staff for over 7 years to improve the accuracy and performance of FLOW-3D using Intel’s constantly evolving architecture and toolsets to meet its customers demand for accurate solutions in less time for larger data sets.

OpenACC on a Roll with Growing Developer Tool Support
Search Results for: cfd
Today the OpenACC standards group announced growing support for OpenACC-supported development tools, and initial results from programmers who have been using the recently-released OpenACC compilers to accelerate research.
Using PGI’s OpenACC compiler, we ported a computational fluid dynamics (CFD) application benchmark to a general purpose GPU-based system,” reported NASA researchers in an upcoming research paper. “OpenACC is a much easier way to accelerate applications than other programming approaches, and we saw an immediate speed up of the benchmark on multiple tests, up to 10X faster compared with a single CPU core-based system.”
I met with members of the OpenACC standards group last week and it is clear to me that Directives are simply a much more efficient way to port codes to accelerators, especially on massive hybrid systems like the Titan Cray XK7.
As evidenced in this SC12 Show Guide, OpenACC will be all over the SC12 show floor next week. Be sure to check out the OpenACC tutorials and BoFs as well as demos from CAPS, PGI, and Rogue Wave. Read the Full Story.
