Attributes

id: Element identification number, (integer>0).
i_marker_id: The ID of I marker.
j_marker_id: The ID of J marker.
is_action_only: A Boolean variable. Select from "TRUE" and "FALSE".; "TRUE": The element applies a force/torque on the I marker but no reaction on the J marker.; "FALSE": The element applies a force/torque on the J marker but no reaction on the J marker.
val: Modifies the magnitude of a constant valued force.
val_expression: Modifies the magnitude of the force vector as a function expression in the XML input file.
usrsub_param_name: The list of parameters that are passed from the data file to the user defined subroutine, specified by usersub_fnc_name.
usrsub_dll_name: Modifies the path and name of the DLL or shared library containing the user subroutine. MotionSolve uses this information to load the user subroutine in the DLL at run time.
usrsub_fnc_name: Specifies an alternative name for the user subroutine SFOSUB.
