BUG: redistributePar -reconstruct: Lagrangian fields are not reconstructed

In $FOAM_TUTORIALS/lagrangian/coalChemistryFoam/simplifiedSiwek, run:

./Allclean
./Allrun-parallel
reconstructPar -latestTime
ls 0.5/lagrangian/limestoneCloud1/

yields: active age coordinates Cp d dTarget nParticle origId origProcId positions rho T tTurb typeId U UCorrect UTurb

Then:

./Allclean
./Allrun-parallel
mpirun -np 4 redistributePar -parallel -reconstruct -latestTime
ls 0.5/lagrangian/limestoneCloud1/

yields: coordinates positions

Note-1: Tested dev c6d9c031, v2112 14aeaf8d, v2106 c15bfde3

Note-2: redistributePar -decompose works as expected.

@Mattijs @mark

added bug label

Hi @kuti - looks like it didn't work in v2112 either. Is that what your comment is saying?

yes - the issue is present in v2112 and v2106 afais.

I don't know when/if this ever worked. Can consider backporting this particular fix to v2112 (@Prashant, @THO).

From my side there is no backporting needed as (out of the box) I don´t know applications at (local customer) that use Lagrangian calculations.

mentioned in commit 3c642833

@Mattijs - yet another place for collated or other file formats....

To repeat the information from the commit:

• the file removal cleanup, which makes reasonable sense for redistribute mode, always forced the removal of the reconstructed lagrangian fields (since all of the non-master fields are empty by definition)!

  Detect reconstruct mode (by using constructSize from the map) to circumvent this logic.
