The message "6DOF angular solver has not converged" means that you should either correct the "Implicit Update" settings or time step size and number of iterations per time step.
In the "Implicit Update" panel, enter the convergence criterion for the 6DOF solver (default 1e-3). If this is not achieved within a time step, reduce the update interval, calculate more iterations per time step, or reduce the time step size.


I hope this helps
