patchAverage does not work

HectorLee · May 23, 2017, 20:30

Hello, everyone~
After running a simulation, I tried to use 'patchAverage' to calculate the average value of scalar T at the outlet (outlet is on the right side of the domain. The type is patch and the value is zeroGradient for T). However, after inputting the command: patchAverage T right, I always got the text:
patchAverage has been superseded by the postProcess utility:
postProcess -func 'patchAverage(name=inlet,p)'
Then nothing happened......Is there anyone knowing why I got this text and how to fix it?

Thanks very much

In newer versions of OF some post processing tools are combined in the postProcess utility. The message gives you how to use it in your case.

@Pi Lee, please read the message you marked bold. As Uwe already told, the patchAverage was replaced or put into the postProcess utility to make maintenance easier and also extensions. If you would just investigate the time writing that tread in reading the message you would probably found the solution yourself. I have no idea if there is any improvement to the error message. However, you made my day because the solution is already there (which you marked bold):

Code:

postProcess -func 'patchAverage(name=inlet,p)'

in your case it is

Code:

postProcess -func 'patchAverage(name=outlet,T)'

Thanks very much, Uwe. Although I got errors at the beginning of using 'postProcess -func', now it works. The correct way is "postProcess -func 'patchAverage(name='right', T)' "

Thanks very much for your explanation, Tobi

Finally it works. I input the command: postProcess -func 'patchAverage(name='right', T)'.
