- can now drop older Test-decomposePar for exploration purposes and simply use -dry-run with the -domains and -method options. - write VTK file instead of volScalarField in combination with -dry-run and -cellDist. Avoids adding any OpenFOAM fields and is usually faster to load. Also easier to rename than a volScalarField would be when exploring multiple decompositions.
