©2026 ANSYS, Inc. 13 Torque Law in the Rocky UI Adds a 1-way constant torque law to model viscous dissipation of particle rotations in Rocky: • Enables applying a rotation-damping torque independent of CFD coupling. • To account for viscous rotational dissipation when particles rotate, even without full CFD coupling. • To align the 1-way constant setup with the existing 1-way Fluent torque law behavior. Golf ball stroked with topspin to curve toward the target, showing a decreasing rotational speed due to viscous dissipation.
