Dear Abaqus User

I am simulating free free  normal mode analysis. I have used Kinematic coupling in my model.  I am consistently getting " Three factorizations in a row failed" error. it also suggests to check the model, It is possible that the model contains the kinematic coupling definition set up in a way that a degree of freedom has neither mass nor stiffness.

Kindly suggest me to overcome this error.

Thanks & Regards
