*SetForce() - symmetric line of action
Sets the value for a symmetric line of action action-reaction force pair.
Syntax
*SetForce(force_name, LEFT|RIGHT, LIN, value,)
    Arguments
- force_name
 - The variable name of an existing LOA action-reaction force pair.
 - LEFT RIGHT
 - If LEFT is specified, the properties are assigned to the left force, and the right force properties are made symmetric to the left force.
 - LIN
 - Keyword suggesting that a linear value is used to specify the force value. With symmetry, only LIN is valid.
 - Value
 - The value of the linear force.
 
Example
*Body(b_frame, "Frame Body")
*PointPair(p_jnc_frame, "Jounce bumper pt. on frame")
*BodyPair(b_uca, "upper control arm")
*ActionReactionForcePair(frc_jnc_bmp, 
 "Jounce Bumper Force", 
 LOA, 
 b_frame, 
 b_uca, 
 p_jnc_frame, 
 p_jnc_uca)
*PointPair(p_jnc_uca, "Jounce bumper pt. on UCA")
*SetForce(force_jnc_bmp, LEFT, LIN, ds.real1.value + ds.real2.value)

Solver expressions, curve data, or user subroutines cannot be used for symmetric force pairs.
