Bulk Data Entry
FORCE1 – Static Force, Alternate Form 1
Description
Used to define a static force by specification of a value and two grid points that determine the direction. It can also be used to define the EXCITEID field (Amplitude “A”) of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 bulk data entries. Additionally, the FORCE1 entry can be defined as Follower Loads in Large Displacement Nonlinear Analysis.
