Error: the target KEYOP11 settings are not the same


    • Adam Dunn

      Hi, I'm getting an error that I don't understand.

       *WARNING*: Node 60215 has been used on different contact pairs (real ID
       246 & 343).  These two pairs will be merged.  Please check the model   

       *** ERROR ***                           CP =      16.578   TIME= 11:56:38
       However, the target KEYOP11 settings are not the same.                 
       *WARNING*: Some MPC/Lagrange based elements (e.g.186353) in real       
       constant set 246 overlap with other MPC/Lagrange based elements        
       (e.g.187783) in real constant set 343 which can cause overconstraint.  

      What does this mean? How can I access contacts by real ID within mechanical?

      Do you have remote displacement and/or remote force loads defined in the model?  Ansys uses contact technology to generate the surface based constraint equations used for these types of loads. The target elements are the master nodes and KEYO(11) is a reference to relaxation method used in the constraint equations.  Refer to the MAPDL Elements Reference Manual for TARGE170 for more information. 

      It appears you have  scoped regions (surfaces and/or edges) that are overlapping and the CEs are conflicting with each other.  You might also have MPC bonded and/or no-separation pairs that are interfering with each other.   

      If that description speaks to your application, can you try to change your scoping or your method of applying these loads to eliminate these overlaps?

        I've rebuilt my model using that advice and its worked, thanks!
