WebbThe default cut-off frequency in Caesar II is 33 Hz, which is too low for predicting the dynamic response for slug flows. The rise time of slug loads is in the order of 10ms, resulting in a minimum input frequency of 50 Hz. Increasing the cut-off frequency increases the accuracy and reduces the maximum calculated response forces in many cases. Webb3.
