Comments
- PARAM, WTMASS is ignored for the
multibody and component mode synthesis (flexible-body preparation) solution
sequences. Unit data for these solution sequences is supplied on the
DTI,UNITS Bulk Data Entry.
- This DTI,
UNITS Data Entry is the same as the UNITS entry.
- If the units defined on the
DTI,UNITS entry are not consistent,
mass unit is ignored, only force, length, and time units are considered in
Explicit Dynamic Analysis (EXPDYN) subcases.
