Stefan Wunderlich 6 Report post Posted December 11, 2017 Hi Mohamad, There is no connection to either the geometry or the starccm setup for the used designvariables (pm1, pm2).So when the designengine is doing the variation, only the values change but nothing more happens. You have to modify your setup in a way that changing a designvariable leads to a changed geometry.Checkout the sample "S-Duct Geometry Variation".
