Hi,
I have model simply supported beam with one end fixed and other end only rest support. At the middle i break one element. When i run dynamic analysis of that system. I received following notification.I have consider lumped mass system.
" Not enough mass DOFs in the model to satisfy the number of eigen pairs requested.Continuing with those that were computed."
When i select consisten mass model above notifiaction won't appear.
Can anyone please clarify why does it so. ?
Thanks
