how to convert pressure values into frequency valu
 

Hi,

i am carrying out analysis of flow past a cylinder.

i came to know that in this analysis even we can determine the noise level surrounding the cylider caused by the disturbances. (It is said that frequency can be calculated by using pressure values.)

If any of you knew how to do this in fluent

or by any other method to find frequency.

please inform me. It will be very helpfull to me.

with regards harry
