Presently, our group has 75 members (up FUN3D Update 1from 28 just a month ago). Our membership Exa Case Study 1roster is diverse both in background and location. COMSOL 2 Your Input 3The wide range of our members’ expertiseincludes application, flow solver and gridgeneration software development, hardwaredevelopment, teaching & training, marketing, More Fun – FUN3D Updaterecruiting, and even outsourcing. Our members By Bil Kleb (Bil.Kleb@NASA.gov)are also geographically dispersed around theglobe (USA, Canada, Italy, UK, France, Sweden, FUN3D 10.5.0 has been released. Features areGermany, Switzerland, India, and China). With documented in the Release Notes section of thesuch a strong start, it is easy to predict that our website: http://fun3d.larc.nasa.govCFD group will continue to grow. Hopefully, thestrong membership will also translate into Case Study - Exabenefits to all members and the CFD communityas a whole.
