Unable to implement moment on the system!

Hi,

I am simulating a model of a structure which has a central rotating shaft and other components attached to it. The shaft is rotating by a motor and hence the other components should rotate with it too. I am facing a couple of problems with this model:

1. When I carry out a Stationary Analysis, it returns the error:'The relative residual is greater than the relative tolerance.'
2. Then, when I try with Time dependent Analysis instead, it computes the results, but incorrectly, as the shaft doesn't rotate but the other components attached to it move under their own weight.

I am unable to understand where I am going wrong. I have attached the model . Any kind of help would be appreciated.

Thanks in advance!

Regards,
Amitosh
