Hello, I keep getting this error after 50% of the time of the run 

I'm using HyperCrash :

 

  • Radioss Error 110  ERROR : RIGID BODY ID=31 UNSTABLE

 

How can I fix this ?

    In general it is because the rbody rotates too much during a cycle, probably due to some other instability, you can set ispher =1 to see if that helps, can you share the model?, I can take a look for you.

    Hello Paul, Thank you for you replay 

     

    I tried to do that but it's still the same problem , and the .out file doesn't show any error , do you think the nodal time step can help to fix this ? 

    Unfortunately I can't share the model
