AutoSPC and RBE2

Hello,

I have a model with solid mesh (tetras) with membrane elements at the surface. All are 2nd order. The part I am analyzing is attached by three bolts, which are modelled as RBE2. The SPC is applied to the master of these. When I run eigenmodes analysis I need the AUTPSPC function in order to get the correct eigenmodes. This creates dof 456 at the slave nodes of the RBE2. Why is this needed? Is there any other way to solve this so that I don't need to use AUTOSPC?
