Advanced Dynamics (NE-L3 Module)


The advanced dynamics module (NE-L3) expands on the FEA analysis capabilities of the NE-L1 and NE-L2 packages. Transient, frequency, response spectrum, random vibration, and complex eigenvalue extraction analysis are all added with this package. This package permits the application of all static loads as dynamic loads.
