VoronoiAnalysisModifyer - Face and Edge Threshold Relative Units
Dear Alex,
At the moment, within the VoronoiAnalysisModifier, when edge and face thresholds are supplied, these refer to absolute units, in the units supplied by the simulation frame.
In the study of certain systems, such as metallic glasses, it is common to read in the literature lines to the following effect:
"In order to minimize the problems of degeneracy and thermal fluctuations, surfaces having area less than 1% of the total area of the Voronoi cell surfaces have been removed", Ref. Mahjoub et al, doi: 10.1016/j.commatsci.2014.09.019
Therefore, it would be advantageous for users to be able to specify these values in fractional or percentage terms.
Regards,
Nick Hamilton

MasterI have updated the user documentation to clarify the role of the edge/face threshold parameters of the Voronoi analysis modifier:
http://ovito.org/manual_testing/particles.modifiers.voronoi_analysis.html
In particular it is now mentioned that they represent absolute values. The option to specify relative threshold values will be implemented as soon as I find some time.

A relative face area threshold has been added as an additional parameter to the Voronoi analysis modifier:
