Negative inertia on node

Hi,

Is this the master node of a rbody. If yes, kindly make Isphere 1 for small rbodies in the model.

Hi @yassinek

If the solution by @gopal_rathore is not helping Try these:

1) Increase the master segment or try repositioning slave nodes

2) You can set the Ignore flag to value 1 from 0 if you are using Type 2 interface. But this may introduce mass addition at the beginning
