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.
