An unknow error ocurred during solution, simulation FWS

      Hi! I've tried to simulate a friction stir welding process on ansys workbench 17, 


      My computer has a i7 7700 HQ, 64 gb ram, but the messeage "an unknow error ocurred during solution" apeared constantly. I already check all APDL codes and the analysis settings. It could be the sub steps i defined in analysis settings? Or the Apdl?


       I use a SOLID 226 element in all the geometry, also the contact and target surface was defined in the conecctions window, this area of contact was defined witch these the apdl codes, the contact between plates.


      keyopt,cid,1,1        
      keyopt,cid,4,3
      rmodif,tid,14,2e06
      rmodif,tid,35,1000


      Also the frictional contact between the shoulder and the surface plates was defined like,

      keyopt,cid,1,1          
      keyopt,cid,5,3
      keyopt,cid,9,1
      keyopt,cid,10,2
      rmodif,cid,9,500e6
      rmodif,cid,14,10
      rmodif,cid,15,1
      rmodif,cid,18,0.95

      I hope someone could help me

      Hi Luis,


      Click on Solution Information, go to Solution Output. In this window use ctrl+F and search "error" / "warning" for detailed messages. It may help to pint at correct section of the code where APDL is failing.

      I think you should modify your code.

      Hi you can find an extremely helpful tutorial on Youtube, which reveals the full set-up in Ansys Workbench



      This helped me a lot


      best regards
