Take your use of dynamic FEA to the next level.

This advanced course on dynamic FEA covers a broad range of solution types, beyond the usual natural frequency and dynamic response methods. This allows more physical phenomena to be investigated and simulated using dynamics in FEA.

Covering topics such as random vibration, shock and response spectra, nonlinear dynamic response, explicit dynamic analysis and complex eigenvalue analysis, attendees will come away with an understanding of the theory behind advanced dynamic analysis techniques, a practical understanding of advanced applications, hints and tips for setting up advanced dynamic analyses, a roadmap for understanding the results, and, perhaps most importantly, an appreciation of the limitations of simulation methods.
