When Do I Need a Dynamic Analysis?

Question

SimScale provides both static and dynamic structural analysis capabilities. When is it necessary to perform a dynamic analysis?

Solution

If your applications involves significant accelerating or decelerating motion, inertial forces will be present and a dynamic analysis is required to capture their effects. For slow moving cases with little acceleration pseudo-static analysis will suffice.

There are two main situations in which engineers apply dynamic analysis on the SimScale platform:

  1. Impact loading, for example drop testing or shock analysis
  2. Oscillatory motion caused by harmonic forcing. Dynamic analysis can accurately capture resonant behaviour when it is experienced.

Important Information

If none of the above suggestions did solve your problem, then please post the issue on our forum or contact us.
