In Simscape Driveline, any use of a clutch causes the solution to not converge

1 vue (au cours des 30 derniers jours)
I've been experimenting with Simscape Driveline for the last week now and so far, every time I try to use one of the standard transmission blocks, or even when I simply try to make a simple model with a planetary gear with a clutch locking the ring, the clutch refuses to solve. Here is an image of my basic test model. http://imgur.com/gw7qENL Here is the error I receive. http://imgur.com/5Ui9e5c For more clarification, the version is r2016b and I am running this on windows 7 - note that I get this error when running on windows 10 as well Thanks for any help I may receive

The following points may help you:
1) If you encounter convergence failures or abrupt driveline state (velocity) changes at or around the instant of clutch state changes, consider reducing the solver tolerances (for a variable-step solver) or the step size (for a fixed-step solver). Set the variable-step solver tolerance or the fixed-step solver step size to the smallest value possible that produces an acceptable simulation speed (not too slow).
2) Very small velocity threshold values and short time lags can degrade numerical convergence or simulation performance. Consider whether you can make these values larger in your simulation.
Also, check the documentation in following link:
Hope this helps!

I have the same issue. Were you able to solve it?
