Time history analysis solves the dynamic equation of motion for extracted nodes of vibration. The results are then summed to find the system results. Loadings are specified in terms of force-time profiles and force sets. The force-time profile defines the load timing. The force set defines the load direction and location. Either the profile or the force set can be used to define the magnitude.
