If checkMesh is executed with the -allGeometry option, then surface
files containing the NCC coverage will now be written out. Coverage is
the ratio between coupled area magnitude and total area magnitude. This
is useful for locating parts of the boundary mesh that are in error.
Errors (such as folds and pinches) typically manifest as a coverage
value that deviates significantly from a value of one.
This is comparable to the writing of AMI patches's weight sums, which
also used to occur when the -allGeometry option was selected.
In parallel the sets are reconstructed. e.g.
mpirun -np 6 checkMesh -parallel -allGeometry -allTopology -writeSets vtk
will create a postProcessing/ folder with the vtk files of the
(reconstructed) faceSets and cellSets.
Also improved analysis of disconnected regions now also checks for point
connectivity with is useful for detecting if AMI regions have duplicate
points.
