Using the THRU format to export bulk data entries

Use the Use THRU Format option on the Formatting options tab of the Export Simulation dialog box to control whether you want to use the THRU format for applicable bulk data entries when you export a Nastran input file. If you select this check box, the software uses the THRU format when it exports the following bulk data entries:

  • ACCEL1

  • ASET1

  • BLSEG

  • BNDFIX1

  • BNDFREE1

  • BOLT

  • BSET1

  • BSURF

  • CSET1

  • GROUP

  • EBDSET

  • MATCID

  • NSM1

  • NSML1

  • OMIT1

  • PLOAD2

  • PLOAD4

  • QBDY3

  • QSET1

  • QVOL

  • RADBC

  • ROTORB

  • ROTORG

  • RVDOF1

  • SPC1

  • SPOINT

  • SUPORT1

  • TEMPP1

  • TEMPRB

  • USET1

Note:

The Use THRU Format option only applies to bulk data entries and does not affect how the SET case control command is exported.
