Hi, 

When I run my solver, the calcul stops, and an error appears about: negative inertia on node 3125451.

Thank you in advance

    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
