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.
