How to output the average pulsating velocity
 

hello everyome!

i recently investigate the cloud cavitation, the cloud cavitation is a instant and periodic cavitation, i want to output the the average pulsating velocity,

My idea is to output the pulsating velocity field at a every moment, and the use the fieldAverage function to calculate the average pulsating velocity.

But now, i don't konw how to calculate and output the the pulsating velocity field at a every moment. Can anyone give some idea?

best wishes!
