Mr Matthew Sale

Student with the University of Sydney


Matthew Sale joined the Bragg Institute in 2010 to work on the computational analysis of Li-ion battery materials. At this time, he wrote the 3DBVSMAPPER program which is capable of analysing the ionic conduction properties of 1,000s of metal-oxide framework materials and other materials.


As of 2015, Matthew is completing his PhD on the computational analysis of functional materials with a focus on density functional theory within VASP. He has performed calculations of the magnetic structure of bulk crystaline solid oxides as well as calculation of ionic conductivity from mean squared displacement/ molecular dynamics and the climbing nudged elastic band method.

Download current stable version: 3DBVSMAPPER_2_02

3DBVSMAPPER is a program that generates bond-valence sum maps and bond-valence energy landscapes to identify ion-conduction pathways for a given test ion species. It uses the application programming interface provided with Materials Studio and the Perl language. The program currently requires Materials Studio from Accelrys; please email us if this is not available to you. Also, please send any comments, problems or bugs about the program to the following email addresses. Improvements to the program are currently in progress and a new version is expected soon.

04/2016 - New program version 2.0 published, see details below...

New features:

  • Points mode - calculate BVS and BVEL values at atomic positions as well as Global Instability Index (GII) and total structure energy 
  • Split +/- field mode - calculates separate attractive and repulsive fields  



  • Updated constants from Stefan Adams for BVEL method. This may have an effect on BVEL calculations containing elements O, Li and B and several other anions 
  • Updated BVS constants from iucr website 
  • Removal of +100 value to all VESTA *.grd output 
  • Overhaul of many subroutines  


Known issues:

  • B-value mixing currently not implemented
