Hello,

I am performing a simulation with the pimpleFoam solver using OpenFOAM v1912. The calculation is running on several processors. I am wondering what is the best practice for a smooth restart. In system/controlDict I am writing out data in binary format, and the variable startFrom is set to “latestTime”.

My main question is whether it makes a difference if I:

1) reconstruct the data from all "processor" subfolders using reconstructPar, delete the aforementioned data subfolders and then rerun the decomposePar, renumberMesh followed by pimpleFoam. This approach is recommended in this post

OR,

2) leave the data decomposed in the separate processor subfolders and imply invoke pimpleFoam.

Option #2 seems like less work to me.

Thank you for your thoughts.
