As the solution progresses, for each written time-step (in each time folder), OF writes the field data for involved variables (U/p/T...). This data is also written on each boundary patch as a nonuniform list (scalar or vector depending on the variable) except for those patches where boundary condition is set to zeroGradient.

Is there a way to force OF to write those out?

Some background to the question: I use functionObject surfaceFieldValue to obtain the data on a patch. I need to assign the values obtained for this patch to another with same number of cells but I noticed that the ordering of the cells varies with no specific pattern for two different computers. (I don't know the reason for this behaviour.) So am trying to see if I can directly use these values from the time folder instead which should have the correct order (because this is what is used in Paraview to render the data). I need p,T and U at this boundary. While, T and U get printed for the patch in the time folder, p doesn't because for this patch I have set zeroGradient as the boundary condition unlike for U and T.

Can anyone give me some clues?

Thanks

Did you end up finding a solution to this?

I have essentially the same problem;
I'm looking for the field values at the outlet patch of a model, so that it can be used for the inlet of another.
Some of these are set to zeroGradient and so values are not written in lists in the time directories.
If anyone knows an alternative way to get lists of these values I'd really appreciate it!

[Edit]: As soon as I posted, this Murphy's law came into effect and I remembered paraview can be used to export a handy csv of all the patch data!

Another way is extracting these values by postProcessing.
