remove penetrations/intersections

Hello,

i try to mesh a Wing for CFD Analysis with VWT. In the Analysis of the Mesh i have a lot of intersections and the automatic fix is not working.

The Endplates are out of Solids. The rest of the Wing is out of Surfaces. I deleted the solids and kept the surfaces of the solids but there was the same problem again.

 

How can i remove those self intersections? (see dropboxfile)

or

Is there maybe a way to trim components with other components and merge the surfaces of those components?

    Hello,

     

    it is probably best, if you go back to the geometry level and intersect the penetrating surfaces before meshing. This will lead to a connected surface mesh without penetrations. Please see the following video link for a description. Please note, that further geometry cleanup and meshing options might be needed in order to achieve a good quality surface mesh.
