Summary0001814: Documentation on scotch decomposition options appears incorrect
DescriptionDocumentation here...

http://cfd.direct/openfoam/user-guide/running-applications-parallel/

...on scotch decomposition options appear to be incorrect. The file referenced for more information on scotch...

$FOAM_SRC/decompositionMethods/decompositionMethods/scotchDecomp/scotchDecomp.C

...does not exist in the current OpenFOAM 2.4.x source tree. I think it should be...

$FOAM_SRC/parallel/decompose/scotchDecomp/scotchDecomp.C

In addition, the default strategy of "b" given under the scotchCoeffs entries in the documentation produces an error when placed into a decomposeParDict. It doesn't appear that the default strategy string is "b".
Steps To ReproduceYou can reproduce this by adding scotchCoeffs and a strategy of "b" to any simulation using a decomposition method of scotch.
TagsNo tags attached.

1. I agree with path correction. Guess, path in documentation migrated there from 1.7.x User Guide.

2. Strategy and strategy string are quite different things. Even if default strategy is "b" (Band method), strategy string (what you put in scotchCoeffs) should be a little bit more complicated (see src/check/test_scotch_graph_map_copy.c from Scotch distribution for example).

Fixed in User Guide in OpenFOAM 3.0.0 and online:

Thanks for bringing this to our attention.
