*SetForce() - asymmetric single component rotation for command sets

Sets the value for an asymmetric single component rotational action-reaction force pair.

Syntax

*SetForce(force_name, , expr_l, expr_r)

Arguments

force_name
The variable name of an existing action-reaction force pair of type SC_ROT.
Type: Varname
expr_l
A number, MDL expression, or solver expression that determines the value of the left force.
Type: real or string
expr_r
A number, MDL expression, or solver expression that determines the value of the right force.
Type: real or string

Comments

The symmetry argument is empty when using a force with asymmetric line of action.

Templex syntax is used in solver expressions. All variables are enclosed in braces {} and the rest of the expression is treated as literal. Solver expressions are enclosed in back quotes. Curve data can be used to define a force by specifying an existing curve, interpolation method, and an independent variable, for example,
crv_name.interp(CUBIC, `{DM}`)

where crv_name is the variable name of an existing curve.
