Hello

I would like to have the output of OpenFOAM files and directories modified and I don't know where to get started.
The solver used for the cases is a settMixingFoam, a modified version of twoLiquidMixingFoam.
The file structure I would like to have is binary volScalarField with no header and no trailer for all fields. And the directory structure I wold like to have is one directory per field, one file per time (not one directory per time, one file per field; as is the default); all inside another directory (e.g. data). For example, the file "$FOAM_RUN/case/14/alpha1" could be "$FOAM_RUN/case/data/alpha1/014".

So I wold like to know:
Is it reasonable to write the directories in this format or is it preferable to change the structure after the case is run?
Is it possible to write and read the velocity field U (volVectorField) as Ux, Uy, Uz (volScalarField)? I believe modifying the files after the case is run would have a significant cost for processing and data storage.
Is it reasonable to write and read binary files without the header and trailer or is it preferable to remove the headers and trailers after the case is run? I believe it would be better to write the files with no headers and trailers, as this could take a significant time to write.
How do I remove the headers and trailers from binary files? I have a case that was already run and I need to do the post processing now.

Thank you


Here is an example of the header I refer to:

Here is an example of the trailer I refer to:
