SOL601 error when I use 'Force balance' option

[SuG89]

Hello,
Please refer to the attached screenshots. I get this error only when the force balance is checked. What could be the reason here? I am using the force balance output to get the net resultant shear force in the bolt region made of solid elements.
Thanks and best regards,
Su

This a documented error with NXN 10.1 which is used by Femap 11.2, it was corrected in NXN 10.2 and later releases.
Femap 11.2.1 and later releases have the updated(10.2) solver and should work fine.

Regards,
Joe
