In most cases it is preferable to avoid using superelements when developing a TAM. In those cases where that is not possible, all instrumented DOF (A-set) must be placed in the residual superelement. This can be accomplished by making the corresponding nodes exterior to all superelements and optionally placing these DOF in the C-set. All the Nastran alters in TAMKIT operate on the residual only, but in most cases will handle models that include upstream superelements.
