  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.
