Reconstruction issue about blastamr HOT 2 OPEN

I had the same issue, never could figure out why it happens as it appears kinda random.

However, I think this is an OpenFOAM issue. I also experienced reconstruct problems with a static mesh for large scale computations on a super computer.

If you have an idea how to solve this, it would be greatly appreciated.

I see.

The problem seems to be originating from a bug in reconstructPar. It is somehow trying to read mesh data of the previous time steps instead of the current one!!!

There is a simple workaround. Reconstruction seems to work if you specify the time as a CLI argument:

reconstructParMesh
for t in $(foamListTimes); do reconstructPar -time $t; done

Or, even better, always reconstruct using distributePar:

runParallel redistributePar -reconstruct

I personally like the second way better. Thanks for reporting this behavior.

I'll keep this issue open; and track progress on fully resolving this bug. If I find time, I'll investigate this further during the weekend.

• add a wiki note about using redistributePar
• switch all tutorials to use redistributePar for decomposition/reconstruction
• fix reconstructPar bug: trying to read some processor meshes from the wrong time folders
