- Using smaller input time steps improves the accuracy of the loading by creating a smaller spatial distribution of load points. This can be important to capture response near supports and other discontinuities in the model.
- Using smaller output time steps increases the accuracy of measuring high-frequency response, particularly for accelerations.
- In most cases keeping the input and output time steps the same size produces the most information
- You should consider starting with larger time steps at first to reduce analysis time while calibrating the model, then reducing the time steps until the response of interest does not significant change anymore.
