tutorial
Example case
See above
What is the current bug behaviour?
- master processor reads ok
- other processors cannot find file
Environment information
- OpenFOAM version :4609aa38
Possible fixes
Introduced with 4609aa38. In uncollated file format the communicator is just the local processor so when the testing was done at the 'worldComm' the broadcast only used the local processor.
