Argument Options Description
option <SID>

No default
SID
Set identification of an SPCADD Bulk Data Entry or, if a SPCADD Bulk Data Entry does not exist with this SID, the set identification of SPC or SPC1 Bulk Data Entries.

Comments

  1. Only one SPC entry can be present for each subcase.
  2. If the SID referenced by the SPC Subcase Information Entry matches with the SID defined for an SPCADD Bulk Data Entry, the information on this entry alone is selected. However, if a SPCADD Bulk Data Entry does not have the referenced SID defined, then any SPC or SPC1 Bulk Data Entries that have this SID defined will be selected.
  3. If present above the first subcase, it is the default for each subcase without an SPC command, with the exception of linear buckling analysis subcases. Linear buckling analysis subcases inherit the SPC information from the referenced static subcase.
  4. SPC may be set to 0 to override the default in subcases where no SPC is required.
  5. SPC must be present for linear static solutions. The SID may be set to 0 to run linear static solutions with no constraints.
