In this work, we propose using edge valence as a quality predictor
when used as a driver for adapting all hexahedral meshes. Edge valence,
for hexahedra, is defined as the number of faces attached to an edge. It has
shown to be a more reliable quality predictor than node valence for hexahedral
meshes. This work presents a general algorithm for predicting edge valence
when used with column collapse and sheet extraction operations without actually
performing the operation. Results have been derived from application
of the algorithm towards the localized coarsening process.
