Dynamic Analysis

Dynamic analysis allows the user to account for the time dependent characteristics of their structure.

For linear dynamics, the initial effort is often to determine the natural frequencies through a modal analysis.

Results are then utilized in a harmonic, shock, seismic, random vibration, or transient simulation to determine deflections, stresses, and strains. For nonlinear dynamics, a direct transient simulation can be performed.
