Calculation DYNAM Pro - Forced Vibrations

How do I choose the correct time step for the integration?


The correct time step depends on the natural frequency of the system or the frequency of the exciting forces.

To achieve a sufficient precision, the governing period T = 1/f is divided in about 10 steps; that is, the time step Delta t is to be such that Delta t < t/10="1/(10f)" =="" 2="" pi="" (10="" omega).="">

Furthermore, you can specify in this definition point whether the results of each time step are to be shown or, for example, only for each fifth time step.
