Hello, I tried to make a motion analysis, but it gives me this failure:

The solver failed to converge. Possible causes are:

1. The solver is failing to achieve the specified accuracy. Relax the Accuracy

   setting in Motion Analysis Properties.

2. If parts in the model are moving quickly, evaluate the Jacobian more often.

3. The mechanism may be getting locked. Start the simulation with a different

   initial configuration or change your motors to get valid motion.

4. If the failure is happening right at the beginning of the simulation, use a

   smaller Initial Integrator Step Size.

5. Try to use a stiff solver like 'WSTIFF'.

6. Try to avoid sharp discontinuities in the model like sudden motion changes,

   force changes or mate activation/deactivation.

7. You may have motors with very high speeds. Try to reduce the motor speed.

8. Make sure that only one motor is driving a given component at any time.

You can simplify the model by combining multiple parts into rigid groups:

   Select the parts in Motion Manager Tree, right-click and choose 'Add to New Rigid Group'

Also, all of the motors starts at the same time, even it should not. Does somebody know?
