*SetForce() - symmetric translational and rotational

Sets the values for a symmetric translational and rotational action-only or action-reaction force pair.

Syntax

*SetForce(force_name, LEFT|RIGHT, LIN, value_fx, 
                                            LIN, value_fy, 
                                            LIN, value_fz, 
                                            LIN, value_tx, 
                                            LIN, value_ty, 
                                            LIN, value_tz)

Arguments

force_name: The variable name of an existing translational and rotational action-only or action-reaction force pair.; Data type: varname
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.; If RIGHT is specified, the properties are assigned to the right force, and the left force properties are made symmetric to the right force.; Data type: keyword
LIN: Keyword suggesting that a linear value is used to specify the force value. With symmetry, only LIN is valid.; Data type: keyword
value_fx, value_fy, value_fz: Numbers, MDL expressions, or solver expressions that determine the value of the translational X, Y, and Z components of the specified side of the force.; Data type: real
value_tx, value_ty, value_tz: Numbers or MDL expressions that determine the value of the rotational forces about the X, Y, and Z axis of the specified side of the force.; Data type: real
curve_name, AKIMA|CUBIC|LINEAR| QUINTIC, `indep_variable`: When using curve data, a curve, an interpolation method, and an independent variable must be specified, where curve_name is the variable name of an existing curve that represents the force/torque characteristic, the interpolation method can be set to AKIMA, CUBIC, LINEAR, or QUINTIC. The indep_variable is the solver expression representing the independent variable along which the force/torque curve is characterized.
spl3d name, AKIMA|CUBIC|LINEAR| QUINTIC, 'indep_var1', 'indep_var2': When using spline3d, a Spline3D entity, an interpolation method, and two independent variables must be specified, where spl3d_name is the variable name of an existing Spline3D entity that would represent the force/torque v/s two independent variables. The interpolation method can be set to AKIMA, CUBIC, LINEAR, or QUINTIC. indep_var1 is the solver expression for the first independent variable. indep_var2 is the solver expression that represents the second independent variable.
`expression`: A solver expression for the force/torque.

Example

*PointPair(p_wc, "Wheel center")
*ActionOnlyForcePair(frc_wc, 
 "Applied force on wheel center", 
 TRANS_ROT, 
 b_wheel, 
 p_wc, mrk_ref)
*SetForce(frc_wc, RIGHT, LIN, 0, LIN, 100, LIN, 0, 
 LIN, ds.real1, value, LIN, ds.real2.value, 
 LIN, 250)
