*SetForce() - asymmetric single component rotation
Sets the value for an asymmetric single component rotational action-reaction force pair.
Syntax
*SetForce(force_name, , TYPE_t_1, TOKEN_t_1, TYPE_t_r, TOKEN_t_r)
Token
- LIN
- Enter a value for TOKEN_t_l and TOKEN_t_r.
- CRV
- Use a Curve to represent the force (torque) behavior. See Comments.
- SPL3D
- Use a Spline3D to represent the force (torque) behavior. See Comments.
- EXPR
- Enter a solver expression that represents the force (torque) behavior.
Arguments
- force_name
- The variable name of an existing action-reaction force pair of type SC_ROT.
- 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
Example 1
*SetForce(f1, , LIN, 30.0, LIN, ds.real1.value + ds.real2.value)
Example 2
*SetForce(2, , CRV,crv_rot ,CUBIC ,`{f2.l.AZ}` , SPL3D, spl_rot,
CUBIC, `{f2.r.AZ}`, `WZ({frc_0.r.i.idstring},
{frc_0.r.j.idstring})`)
Example 3
*SetForce(f3, , LIN,30.0, EXPR,`100*{f3.r.AZ}`)
Context
Comments
The symmetry argument is empty when using a force with asymmetric line of action.
To specify non-linear properties for the torque in any direction, a solver expression, curve data, or spline 3D data can be used. When using solver expressions, Templex syntax is used and all variables are enclosed in braces {} and the rest is treated as literal.
The QUINTIC interpolation method is supported for MotionSolve only.
