Re: Using remote masses in vibration analysis
I has this error a few years ago. From what i can remember my moment of inertia values for the remote mass were zero. I just entered some arbitrarly small value (for the moment of inertias) to solve the problem. Then it worked

Re: Using remote masses in vibration analysis
I tried that but unfortunately it made no difference.
( For additional info, the model works ok if I suppress the remote mass.)

Re: Using remote masses in vibration analysis
that's odd
Have attach a simple model with remote mass. When Ixx Iyy Izz =0 zero fails to run
And not zero runs. Using Sw 2010.
Can you post a simple model back and I'll play with it . 2011 files ok to Jst have to test them at home later.

Re: Using remote masses in vibration analysis
Actually if Lxx,Lyy,Lzz have values but Lxy,Lyz,Lxz are left at zero the error does not occur.
I must brush up on inertial properties of solids.

Re: Using remote masses in vibration analysis
Glad it works.
The Lxy Lxz Lyz properties have to be less than the Lxx, Lyy, Lzz. or the error occours.
There is a reasonably good article on Wikipedia on Principle Moments of inertia.
