common error on Femap: negatives pivots
common error on Femap: negatives pivots
(OP)
Hello , I am new on Femap
I've often the same error on femap : negative or excessive pivot on the DOF listed ...
I know it's a constraint problem but I don't know how to fix it.
What I 'm supposed to do if the error message says " Excessive pivot on the DOF R3 of the point 42"
Thanks :)

It's a simple model : One beam with the right end fixed and connected (at the left end) to a second beam with a Cbush element . Then I apply a torque to the right end of the second beam.
I want to bend the strucure (like closing a book)
RE: common error on Femap: negatives pivots
you're applying torque, and you want the beams to "close like a book"? does "torque" mean a load (in-plane) causing torque about the axis where the beams join ? you're not running linear statics are you ? (since you have a dynamic problem)

I tried applying a load but I have the same error message and I don't know how to follow the displacement of the beam. Then I tried with a torque.

Check your units coherence (Material: young modulus...) and the C-BUSH stiffness you defined on the property.
