How can I calculate fieldAverage in post-processing?
I have got results of a chtMultiRegionFoam (2.0.x) simulation and I'd like to calculate a fieldAverage of T in a given region. Does anybody know how to do that?
I know, that it is easy with function objects... but how do I call those during post processing?
Thanks a lot for your help!
in my experience, nothing is easy in OF!
I had a similar problem a couple of months ago with a simple case (no multi region and stuff). Always start from the simplest problem and advance forward from that point - I nice advice that I always forget ...
I checked the work around in my multi region case and the solution is:
- make a separate file for post processing in the systems folder
- this file should contain the FoamFile header and the functions.
- didn't figure it out how to handle multiple domains simultaneously, so stick with one
- the simpleFunctionObject worked for me, other postproc sampling didn't
thanks for the reply. I was not aware of execFlowFunctionObjects. In my version of OF it does not accept the options -region and -noFlow which is why it won't work for my current problem. But in the future I will use OF 2.1 and there the options are available!
Thanks again for the hint!
All the best,
I have 2.0.x as well so this shouldn't be an issue. Maybe an update to your current 2.0.x would solve the problem so make a git pull and a quick rebuild.
