Resultant of all inertia nodal loads in a steady-state transport analysis. The node set prescribed for this history output request must have only one member.

SSTSRF

SSTIRM

Field: no  History: yes  .fil: no  .dat: no  

Resultant moment of all inertia nodal loads in a steady-state transport analysis. The node set prescribed for this history output request must have only one member.

SSTSRM

Field: no  History: yes  .fil: no  .dat: no  

Resultant moment of all inertia stabilization loads in a steady-state transport analysis. The node set prescribed for this history output request must have only one member.
