Issue created Jan 10, 2022 by Mattijs Janssens@MattijsMaintainer

BUG: mapFieldsPar does not like old-time fields & does not write uniform/ directory

Summary

mapFieldsPar does not map old-time fields. Also does not write uniform/ directory (but should it?)

Steps to reproduce

  • copy pimpleFoam/RAS/pitzDaily
  • change ddtScheme to backward;
  • change 'stopAt' to 'writeNow'
  • run for one iteration in parallel
  • map results back to original:
mpirun -np 2 mapFieldsPar -parallel ../pitzDaily_junk -sourceTime latestTime

This seems to generate some sigFpe or illegal values in k, epsilon.

Example case

See above

Environment information

  • OpenFOAM version : v2112

Possible fixes

  • was thinking it might be the _0 field being auto-created but not initialised. Then when mapping _0 it would load this auto-generated field and crash. However this does not seem to be the case.
