Quasi-Static events

With a Quasi-Static event, the software calculates the static response of your model to one or more simultaneous time-varying static excitations. The excitation for a Quasi-Static event must consist of distributed attachment modes generated in an SOL 103 – Response Dynamics solution. For more information about distributed attachment modes, see The modal model.

In the Response Dynamics solution process, you scale the static excitation using a unitless scalar time function. The software calculates the response at each instant in time by linearly combining (superposing) the distributed attachment modes. Only the model's stiffness is considered in the calculation; time integration is not used. These simpler calculations allow the software to process the event quickly, especially when it includes a large number of modes.

This event type is useful if you are only interested in static results and need faster solution performance than a full dynamic solution.
