Transcript of "Issue3 07 2008"

  1. 1. July 2008 Issue 3 L INKED I N CFD A networking forum for CFD professionals Membership Report Inside This Issue Membership Report 1 As reported in previous newsletters, our group Pointwise User Meeting 1 membership is growing rapidly. Currently, we have Career Opportunity 1 227 members in our group. Interestingly, our Google Discussion Group 2 membership is spread across the globe as well as Upfront CFD 2 across the spectrum of fields associated with CFD. Your Input 3 Somehow we need to harness the power of this Your Help 3 group by devising a database that shows how each member is associated with CFD and what is the expertise of each member. Career Opportunity Research ScientistPointwise User Meeting Combustion Research and Flow Technology, Inc. (CRAFT Tech) has openings for energetic and motivated individuals with experience inPointwise, Inc. is pleased to announce the Computational Fluid Dynamics (CFD). MS/PhD inPointwise User Group Meeting 2008 will be held at mechanical/aerospace engineering preferred, BS withthe Embassy Suites Hotel in Downtown Fort Worth at least 2 years direct experience will also beon 5-6 November, 2008. The meeting will include considered. U.S. citizenship is required. Backgroundsspecial Pointwise and Gridgen training seminars, in grid generation/adaptation, turbulence modelingpresentations by Pointwise staff on new product and/or LES, DSMC, combustion and/or multi-phasedevelopments, exhibits by our partners, and user flow a plus.

  2. 2. Hold the emailNow, you don’t need to send another mass email to and Inventor all came out approximately the samethe group. A Google discussion group was recently time and have literally changed the way manycreated (http://groups.google.com/group/cfdlinked) people look at 3D modeling, in general. The firstfor members that need to communicate with entire step was to expose structural and thermal FEA togroup. Many have already joined and you can to by the MCAD community. Products like CosmosWorksclicking on “Apply for group membership“ on the group and Design Space were easy to use, gave reasonablypage. This discussion group should eliminate the accurate results, but most importantly opened theneed to send a mass email requesting help. Please eyes of engineers to help visually drive design.refrain from sending any mass email to the group Some of the key areas that were affected.and consider using the discussion group for your 1.

All of the codeshave become easier to use, but the fact is most ofthem are still being developed with the analyst inmind.It is not much different than it was in the broaderStructural FEA market. There was a time whenmany people felt that the easier the product was touse, the more you compromised accuracy. Prettysilly to think about that now, but it was a fact a fewyears ago.
