Hello,

I have a case with many (hundreds) of patches that I would like to report values for (as an area average, for example).
What would be the best way to do this? I know I can use a surfaceFieldValue with a regexp for the patches, but it averages all the patches together rather than reporting them independently.

Does anyone have any clever ideas? I can't feasibly make a function object for each patch, and I'm trying to build an efficient workflow here for future cases.

I can resort to probing values at points, but that causes other issues and won't be as accurate.

Hi,

You could use a bash script with the "foamDictionary" command to automatically set the patch names and run the surfaceFieldValue function.

#!/bin/bash

# Define list of patches
yourListOfPatches=("patch1",..."patch100") #

# Loop through patches
for i in ${!yourListOfPatches[@]}; do
	#Set patch name in "surfaceFieldValue" dict (not exact syntax)
	foamDictionary system/surfaceFieldValue -entry surfaceFieldValue1.name -set "${yourListOfPatches[$i]}"
	# Run sample dict
	simpleFoam -postProcess -func sample

If your patch names look something like "patch1, patch2, ...,patch100", it should be easy to define the list. If your patch names are inconsistent you could read them from the boundary file and write them to the list (again with foamDictionary).

There is probably an easier way but this should work.
