Hello all,

 

I am attempting to use some RBE3 elements to apply loads and I am receiving this error:

 

 A fatal error has been detected during input processing:

  *** ERROR # 774 ***
  When a grid's component has no stiffness, then that component
  cannot be an independent d.o.f. in an RBE3.
               RBE3 id = 270584
               grid id = 326669
   weighted components = 123
  max d.o.f with stiff = 1
 

Would greatly appreciate some advice regarding this. Thanks

    Your rbe3 has a free leg. Check F10>1d
