In OF v1712 you have implemented the Barycentric particle tracking including a backward compatibility (which is great): the barycentric coordinates are written to the file 'coordinates' and, in case you have the writeLagragianPosition set to 1, the normal positions to 'positions'.

I found however, that in case you run a LPT case in parallel and then want to reconstruct the fields, only the coordinates are reconstructed, and not the positions, which means that you still can not read the particles into ParaView (which only reads the positions file, and not the coordinates file).

As a workaround I found that in case I do the reconstruction with a OF version older then v1712, the positions get reconstructed and not the coordinates. In that case you can read the particles into paraview, but then you lose some data because you do not have the coordinates file anymore.

Would it be possible to have both the 'coordinates' and 'positions' file from the lagrangian particles to be reconstructed, that would avoid having to deal with reconstruct the data two times (one time for the coordinates with the new version, on time for the positions with an old version)
