my Assamble Model (Karamba3D) is not running korrectly and I can’t figure out why. I have tried to cull duplicates but its not workling.
The Error Message is:

1. Supports with the following indexes: 2,34,66,67
   There are already supports defined identical degrees of freedom at the same position. In case you sum up the reactions of all supports this will lead to a wrong resultant reaction force.
