Hello everyone, I am doing a simulation of a vent flow by ANSYS CFX. I want to know the Standard Deviation of velocity, for example, on a plane. It seems that CFX Post did not provide a function to calculate the Standard Deviation. What should I do to get it?
The Standard Deviation = sqrt[sum((Xi-a)^2)/(n-1)], in which, a is the average of Xi, n is the number of Xi. The problem now is that we don't know the how many of Xi is there on the calculated plane. I will appreciate you very much for any information. Thank you very much, BalanceChen |
