Trouble meshing full vehicle model

Hello everyone,

 

I am attempting to mesh a full vehicle model of an open-wheel racecar in Hypermesh, for export to Virtual Wind Tunnel. So far, I have been successful in meshing the model without the suspension components and wheels. However, when the suspension and wheels are attached, it seems like there are way too many intersections/penetrations and free edges to fix. Does anyone have any tips on how to cleanup the geometry to get rid of most of the intersection and free edges issues?

 

Thanks for your help,

Tommy

    Hi Tommy,

     

    For meshing any model it is always advised to follow the following steps:

    1. Clean up the geometry: Find and remove duplicate surfaces, free edges, pin holes if any. You can do it from Geometry panel: Geom > defeature

    2. Mesh the cleaned geometry.

    3. After meshing check for intersections/penetrations. If intersections/penetrations are present:

    a. Repeat step 1 and mesh it again.

    b. Delete the local mesh (defective elements) and rectify it manually {usually not recommended}

     

    Thank You
