Command-line option handling:
+ If -all specified or no refineMeshDict exists or, refine all cells
+ If -dict <file> specified refine according to <file>
+ If refineMeshDict exists refine according to refineMeshDict
When the refinement or all cells is selected apply 3D refinement for 3D
cases and 2D refinement for 2D cases.
To compile with 64bit labels set
WM_LABEL_SIZE=64
in ~/OpenFOAM/dev/prefs.sh
source ~/.bashrc
then Allwmake in OpenFOAM-dev.
This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt
If WM_LABEL_SIZE is unset or set to 32:
WM_LABEL_SIZE=32
the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt
Thus both 32bit and 64bit label builds can coexist without problem.
