When I generate flexbody in flextools, I had a problem. 

 *** ERROR # 176 ***
  A dependent d.o.f. of rigid elements is constrained in an SPC set.
         grid id = 52
       component = 1
      SPC set id = 0
  My .fem modal have rbe3 element to specify load, node (id 52) is it's dependent node. I don't know how to solve this problem. can anyone help me? thanks.

Hi Phat,

Flexible bodies for MotionSolve need to have RBE2 as rigid elements. RBE3 won't work.

Can you try switch the element type to RBE2 in HM and create it again?
