Presently, our group has 75 members (up FUN3D Update 1 from 28 just a month ago). Our membership Exa Case Study 1 roster is diverse both in background and location. COMSOL 2 Your Input 3 The wide range of our members’ expertise includes application, flow solver and grid generation software development, hardware development, teaching & training, marketing, More Fun – FUN3D Update recruiting, and even outsourcing. Our members By Bil Kleb (Bil.Kleb@NASA.gov) are also geographically dispersed around the globe (USA, Canada, Italy, UK, France, Sweden, FUN3D 10.5.0 has been released. Features are Germany, Switzerland, India, and China). With documented in the Release Notes section of the such a strong start, it is easy to predict that our website: http://fun3d.larc.nasa.gov CFD group will continue to grow. Hopefully, the strong membership will also translate into Case Study - Exa benefits to all members and the CFD community as a whole. By Rich Oasis (ROasis@exa.com) ENGINEERING THE ENGINE OF THE FUTURE - AGCO Top 3 CFD Pain LOOKS TO EXA FOR AERO/THERMAL ENGINE SIMULATIONS By Greg Burgreen (burgreen@SimCenter.MsState.Edu) Five years ago, with over thirty years of engineering Optimal LLC (www.o-ptimal.com) has received a experience, David Bloch joined AGCO as their Chief strong response to its CFD Pain Survey Engineer of Engine Installations. His team’s primary (http://www.o-ptimal.com/survey.html) that responsibility—to find a way to design and fit inquires about significant pain or bottlenecks engines within a small underhood compartment associated with CFD applications. The current top while balancing optimal performance, new space three CFD pains include: 1) Software expense (71% demands required for Tier 4 emissions-reducing respondents indicating intense or searing pain); 2) equipment, and styling requirements. With the Mesh generation (67%); and 3) Geometry larger farms growing at an average of 30% per year, creation/clean-up (65%). Do these findings the market potential for heavy equipment sales is resonate with your own experience? We invite you enormous, and companies that can offer reliability to contribute your own unique response to our and efficiency will get the orders. Block knows his survey. This is your opportunity to provide direct input toward software aimed at reducing your CFD Continued on Page 2 pain.

Case Study - Exa (cont.) department is key to the success of AGCO’s market “The ability for AGCO to use our fully-detailed share growth and stated, “Cutting-edge geometry, with Exa’s PowerFLOW and PowerCOOL engineering of the underhood is now a critical part applications, was very reassuring, as we knew for of the design process. AGCO has made engineering the first time the results would reflect the extremely the best equipment for our customers our number complex underhood geometry. We’ve found Exa’s one priority.” results to be fast and consistently accurate.” Bloch also discovered great value in Exa’s On Demand MOVING TO VIRTUAL DESIGN servers where PowerFLOW and PowerCOOL Traditionally, David Bloch had used a series of simulations can be turned around in record time as physical tests to map out and analyze engine CPU hours can be picked up as needed. David Bloch airflow and thermal management issues, often commented, “To have CPU-capacity ready and running up to twenty iterations for each proposed waiting is a luxury most companies cannot afford. design. In the end, hundreds of thousands of Exa has made it easy for us to perform geometry dollars and thousands of man hours were required iterations in record time.” to run, analyze, redesign and run again each physical model test. With multiple platforms and numerous variations of engines and cooling packages to support for each platform, Bloch quickly realized that CAE would be required to make his deadlines, streamline the process and reduce his budget. He began researching commercial computational fluid dynamics (CFD) packages. Unfortunately, Bloch was immediately disappointed. “The first software application I investigated was not user-friendly, and in our numerous attempts to run thermal and To read the entire AGCO case study, please visit airflow simulations, we never got acceptable www.exa.com or email info@exa.com. results; often, no results,” Bloch stated. “That’s when I began to work with Exa.” Conference SERVICES & AN ON DEMAND SOLUTION By Daniel Ericsson (daniel.ericsson@comsol.com) After evaluating the extensive list of simulations The COMSOL Conference 2008 is the fourth annual required, and with his team already being pulled in conference highlighting multiphysics modeling and many directions, Bloch quickly came to the simulation using COMSOL. The conferences take conclusion to try Exa’s services and its On Demand place at 11 different locations and the Conference option. “I was pleased to finally find a one stop proceedings will be distributed to over 100,000 solution that not only handled both our underhood engineers and scientists world wide.
