Could you explain what is  dof 43 this warning message..I used rigid elements, contact non linearity, Not used Material non linearity

 

*** INFORMATION # 815
 The total number of rigid elements, whose rotational dependent d.o.f.
 are removed because there is no need to constrain those d.o.f., is 43.

    Usually it should be no problem to define a load at the independent node of a RBE2 element.
    Probably one or more nodes are not equivalenced in the model. You can check if you have free nodes or free elements in tool panel -> check elems -> 1D. If there are nodes shown, you should fix that with equivalence.
