- renumberMesh now has -dry-run, -write-maps, -no-fields,
-renumber-method, -renumber-coeffs options.
* Use -dry-run with -write-maps to visualize the before/after
effects of renumbering (creates a VTK file).
* -no-fields to renumber the mesh only.
This is useful and faster when the input fields are uniform
and the -overwrite option is specified.
* -renumber-method allows a quick means of specifying a different
default renumber method (instead of Cuthill-McKee).
The -renumber-coeffs option allows passing of dictionary content
for the method.
Examples,
// Different ways to specify reverse Cuthill-McKee
* -renumber-method RCM
* -renumber-coeffs 'reverse true;'
* -renumber-method CuthillMcKee
* -renumber-coeffs 'reverse true;'
* -renumber-coeffs 'method CuthillMcKee; reverse true;'
// Other (without dictionary coefficients)
* renumberMesh -renumber-method random
// Other (with dictionary coefficients)
renumberMesh \
-renumber-method spring \
-renumber-coeffs 'maxCo 0.1; maxIter 1000; freezeFraction 0.99;'
// Other (with additional libraries)
renumberMesh -renumber-method zoltan -lib zoltanRenumber
COMP: build zoltan renumbering to MPI-specific location
- zoltan and Sloan renumbering are now longer automatically linked to
the renumberMesh utility but must be separately loaded by a
command-line option or through a dictionary "libs" entry.
ENH: add output cellID for decomposePar -dry-run -cellDist
