Use the Torque node to exert user-defined torque on grains. All torque defined in the model are added together to compute the total torque on the grains.

Enter values or expressions for the Torque in body-fixed frame τ (SI unit: Nm) in 3D. The default values are 0 Nm.

In 2D, enter values or expressions for the Grain Torque τ (SI unit: Nm). The default value is 0 Nm.
