Comments

  1. 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.
  2. This DTI, UNITS Data Entry is the same as the UNITS entry.
  3. 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 subcases.
  4. This card is represented as a control card in HyperMesh.
