    Star-CCM+ frontal area issue

    Hi, Im having an issue with the frontal area report of star-ccm+ in a 3d external flow simulation over an ahmed body. I am doing a half body simulation which would lead to a frontal area around .056 m^2 but I am getting .208 m^2. I am selecting all parts in the region that make up the ahmed...

    Trouble creating watertight geometry

    Thank you for the replies. I eventually got the body to become watertight. Unfortunately that required rebuilding half of the car. And yes as im using star-ccm+ I couldve used surface wrapper but preferred to have a solid body to make aerodynamic modifications easier in the future

    Trouble creating watertight geometry

    Hi, I have an imported .iges model that I need to create watertight to run CFD on it. I am designing an aerodynamic package for the car. But first I need to get the general model working. It has over 5000 surfaces after importing and has me stumped after 2 days of working on it. I keep getting...
