Fusion Non-linear Analysis Bisection Error

Anonymous
Not applicable

When I run my analysis at different load steps from 1000lbs to 5000lbs everything solves properly. However, once I place 10,000lbs of load I receive a bisection failure (Shown Below). Does anyone know how to fix this issue and explain how to prevent it in the future? 

 

*Error: MAXIMUM NUMBER OF BISECTIONS PERMITTED REACHED              
 Cause  : The bisection limit specified on the NLPARM (static solutions) or a TSTEPNL (transient
              solutions) Bulk Data entry for the current load increment has been reached (default
              5).
 Action : Increase the bisection limit and/or investigate the reason for the load bisection.See
              message E5075 above.

Hello @Anonymous,

 

could you try increasing the "Number of steps" in the Study Settings?

I have increased the steps up to 60 and am getting the same failure type. I
have not tried going higher as I do not know the max/recommended limit of
steps in a simulation. If you think i can go higher let me know, i really
need this to solve.

Thank you for a response!

Hello @Anonymous,

 

You could try going higher to about 150-200, but try it in increments. If you are still having issues, are you able to share the model?

Please refer to the link below on how to share Fusion 360 models.
