Definitions

Field Contents SI Unit Example
ID Motion set identification number.

(Integer > 0)
TID Identification number of a TABLEDi entry that defines motion scale factors versus time. The motion in the VALUE field is multiplied with the scale factors to determine time-dependent motion on the joint degrees of freedom.

Default = blank (Integer > 0)
TSTIME Switch for time duration of the data from the table defined in TID. 3
TOT or 0
Uses total time to look up table data.
SUB or 1
Uses subcase time to look up table data.

Default = TOT
JIDi Identification number of a JOINTG Bulk Data Entry on which the motion is to be applied.
DOF Degree of freedom component number.

No default (1 ≤ Integer ≤ 6)
VALUE
Real
Motion value to be applied on the identified degree of freedom for the specified JOINTG joint. For more information, see the corresponding joint description on the JOINTG entry.
FIXED
The corresponding degrees of freedom of the JOINTG entry are fixed.

No default

SET Keyword indicating that the corresponding JID refers to an element set which contains a set of JOINTG entries.

Default = blank

Comments

  1. The MOTNJG Bulk Data Entry can be referenced in the corresponding MOTNJG Subcase Information Entry.
  2. If a MOTNJG Bulk Data Entry is not referenced in any subcase, then it is not used in the solution.
  3. TID and TSTIME are supported for:
    • Implicit small and large displacement nonlinear static analysis.
    • Implicit small and large displacement nonlinear transient analysis.
    • Explicit dynamic analysis.
  4. MOTNJG is also supported for normal modes (MODES) analysis. Any nonzero motion value is ignored, and zero motion is always applied instead. Two or more subcases can reference different MOTNJGs, but the motions must be applied on the same joint DOFs.
  5. MOTNJG with JID and SET are supported for both implicit and explicit analyses.
