These operations typically result in 50% of the reduction cost and are not needed in the fixed-boundary data recovery operations described in the next paragraph.  After this operation has been completed, the keyword SELANG will appear in the database dictionary, indicating that the [<em>P<sub class="subscript">a</sub></em>] stored there is incomplete, and should not be summed into the downstream superelement, because System Fatal Message 4252 will be issued.

This output may be obtained as soon as the superelement is successfully generated and reduced and does not require that the entire model be assembled.  In superelement statics, the solution is the component due to the {<em>u<sup class="superscript">o</sup><sub class="subscript">o</sub></em>} vector, i.e., a fixed-boundary solution.  In superelement modes, the solution is the uncoupled eigenvectors of the component.  If PARAM,FIXEDB,-1 is specified in the Bulk Data or in the residual structure subcase, the modes of the residual structure will not be computed.  For a printout or plotting of the component mode eigenvectors it is recommended that PARAM,FIXEDB,-1 be specified in the Bulk Data Section or above the subcase level in Case Control.  If the modes of the residual structure are desired, then PARAM,FlXEDB,0 should be specified in the residual structure subcase.  Exterior degrees-of-freedom listed on SECSETi and SESUP entries are free, and those on SEBSETi degrees-of-freedom are fixed.

                  <p class="para_td">With PARAM,SERST,AUTO or MANUAL, all superelements will be processed through Phase 0 (see <a class="links" href="javascript:void(0)" onclick="top.popUpPage('User/index.html?goto=User/14ref37867_76.html&vars=-aux,-home','linkInter','menubar=yes,status=yes,resizable=yes,toolbar=yes,scrollbars=yes,location=no,directories=no');return(false);">&ldquo;Superelement Analysis&rdquo;</a> in the <em>NX Nastran User&rsquo;s Guide</em>).  This phase includes execution of the sequencer module (SEQP), initial superelement processing (SEP1), and initial geometry processing (GP1 and GP2) modules, which can result in significant CPU overhead.  If this overhead is not desired, then PARAM,SERST,SEMI will limit Phase 0 and Phase 1 to only those superelements specified on the SEMG, SELG, SEKR, SELR, SELA, SEMA, SEMR, and SEALL Case Control commands.  If none of these commands is entered, then execution will skip Phase 0 and 1.

If PARAM,SERST,SEMI and no SE-type command is specified for the residual structure, then, by default, its modes will not be recomputed.  This logic is intended for restarts from SOL 103 into one of the modal solutions.  If, however, the modes have not already been computed or need to be recomputed, then PARAM,SERST,RSMDS must be specified to force the calculation of the residual structure modes. </p>

Also, with this technique, databases are attached with the DBLOCATE File Management statement rather than the RESTART File Management statement.  In general, these options are not recommended because they disable the automatic restart capability, which compromises the database integrity to the same degree as in the unstructured solution sequences. </p>
