    You probably have two rigid (RBE2) elements that share a dependent node.  This is not allowed.

    In the example below, the dependent nodes are labeled in white.  RBE2 elements 101 and 102 share dependent node 56.

    Modify or delete and remake the rigid elements so that they do not share any dependent nodes.
