The problem that detected the problem contained numerous superelements. The user incorrectly specified the boundary nodes of a later superelement which caused the boundary nodes of an earlier superelement to be inactivated. Only the boundary nodes of a superelement are active during a STIFFNESS ANALYSIS or PERFORM ASSEMBLY command - all internal nodes are inactivated. Workaround: The user must check and correctly specify the boundary nodes of all superelements. Applicable Sections of the Documentation: Definition of Superelement - Section 2.3.11.1 of Volume 3 of the GTSTRUDL User's Manual. Rev. 2.2 *** END OF DOCUMENT ***
