The event-to-event analysis method has been improved for better handling of equilibrium unbalances. Additional controls are available for this non-iterative method.The speed of solution using the multi-threaded solver has been substantially increased for direct-integration time-history and other multi-step load cases.

The recovery of plotted and tabular results from nonlinear static and direct-integration load cases is now significantly faster. Results include deformed shape, force and stress values, and hinge states.

The parametric PMM hinge has been enhanced to provide better convergence behavior in sensitive systems.
