The Rot Properties tab on the Forces panel allows you to define the components of a force with respect to a reference coordinate system.  Action and direction options can be set in both the Connectivity and Translational/Rotational panels.

Forces panel - Rot Properties tab

Translational, rotational, and transrotational forces each require a reference coordinate system.  This can be defined from the Connectivity tab.

Use:

To:

Ref Marker

specify the local reference frame of the force.

The magnitude of a force component can be defined using a constant value, math expression, or template expression.

For:

Enter:

Tx, Ty, Tz Linear

constant rotational force.

Tx, Ty, Tz Curve

rotational force expressed in the form of a torque vs. displacement curve which is a function of a set of independent variables.

Tx, Ty, Tz Spline3D

select AKIMA, CUBIC, LINEAR, or QUINTIC under Interpolation and specify an expression each under Independent variable X and Independent variable Z.  Resolve the 3D spline by clicking on the Spline3D collector and selecting a Spline3D entity from the Select a Spline3D dialog.

Tx, Ty, Tz Expression

rotational force expressed in the form of a solver function.

Non-linear force properties may be defined using curves or expressions.
