Many dynamics analyses involve general FEA models. We have
constructed detailed 3D models to obtain natural frequencies,
forced response, and stresses. Examples include:

Component vibration and stress, such as for blades and disks, for design
and life prediction
General
structures
pump
assemblies
piping systems
shafts and
housings
complete packages and skids
Isolation system design
specification/design of effective supports
6 degree-of-freedom natural frequencies
predictions
of isolation effectiveness
analysis of individual isolation components for dynamic properties
