This request element stores the Force_SpringDamper element forces into column vectors F1 through F8 of the request "frc-expr".
Arguments
- id
 - The ID of the Force_SpringDamper element.
 - jflag
 - 0 returns force acting on I marker.
 - component
 - 
                              
- 1
 - returns the force magnitude.
 - 2
 - returns the force x component.
 - 3
 - returns the force y component.
 - 4
 - returns the force z component.
 - 5
 - returns the torque magnitude.
 - 6
 - returns the torque x component.
 - 7
 - returns the torque y component.
 - 8
 - returns the torque z component.
 
 - RM
 - The reference frame in which components are reported. RM=0 implies global frame.
