    Modal Transient Response (SOL 112) - Initial Conditions Not Working?

    Happy Friday all, Sorry in advance for the long-winded explanation. I'm dealing with an issue regarding SOL 112 (Modal Transient Response) which I'm hoping to receive some feedback on. I've made a simplified model (see attached) to test the behavior. The model looks like the letter "T" with...

    MPC Forces Not Making Sense

    Hi all, I have an interesting problem that I've run out of ideas on. I have a model in SI units that includes a large RBE3 with a mass element on the dependent node, and four equally spaced independent nodes connected to zero length pbush spring/damper elements. Each pbush element is then...
