Dynamic Analysis Training

---

Advanced discussion of the use of dynamic analysis. Topics include frequency, transient, and random response analysis. Students are taught how to setup the various inputs and interpret the results.

Prerequisites: Proficiency in the use of Femap and basic Nastran knowledge
Length: 3 Days
