6.3. Multistage Expansion and Postprocessing Tips and Limitations

Keep in mind the following tips and limitations while postprocessing multistage results:

  • If you compare to a full 360° model, be sure to activate powergraphics in both cases (/GRAPHICS,POWER).

  • If you look at equivalent strains, be sure to issue AVPRIN,,EFFNU first.

  • Energy postprocessing is not supported (PLESOL,SENE).

  • Reaction forces calculated using the FSUM command are incorrect.

  • Duplicate sectors remain in the database but are suppressed during an initial expansion. Subsequent selection of nodes or elements may cause the duplicate sector to appear.

  • The nodes and elements of the base sector are expanded to other sectors of interest, resulting in considerable memory usage. Analyses with numerous stages and elements may result in poor performance. For better performance, run such analyses using the Mechanical Application (See Multistage Cyclic Symmetry Analysis in the Mechanical User's Guide).

  • Nodal averaged results (NAR) are not supported for multistage expansion.

  • Since all expanded nodes and elements of a specified stage and sector are automatically selected after expansion, regardless of selection status prior to the expansion, you must repeat any desired selections following the expansion.

  • Expansion of summable (PLESOL,SMISC or PRESOL,SMISC) and nonsummable (PLESOL,NMISC or PRESOL,NMISC) quantities is not supported.
