Problematic Inflation Mesh

      Hi all,


       


      I'm doing a Fluent sim on a basic Ahmed body and I'm encountering problems with creating an even inflation mesh.


      I wish to create an inflation layer over the body and on the road surfaces.


      I have made this work before in previous sims, however I can't seem to figure out what I'm doing wrong this time. Is there something I've missed in the DesignModeller step of the sim? (I'm using Program controlled inflation with First Aspect Ratio, and yes I have selected 'Include' in program controlled inflation for the body and road surfaces under the Named Selections tab).


       


      The attached photo shows what I'm getting - an inconsistent inflation layer that doesnt form on the road or body underside surfaces.



       


      Any help is appreciated!
