The package contains the C++ source code, example files, miscellaneous utilities, and documentation. The package also contains the latest version of Voro++ library. On Linux, Mac OS, and Windows (using Cygwin), the compilation and installation can be carried out using GNU Make.

Step by step compilation instructions:

  1. Download and unpack the provided Zeo++ package (the following commands will create zeo++-0.2.2 directory containing the Zeo++ code; Voro++ library will be placed in one of subfolders (zeo++-0.2.2/voro++)):
  2. gunzip zeo++-0.2.2.tar.gz
    tar xvf zeo++-0.2.2.tar
  3. Compile Voro++ library (you may need first to review file in zeo++-0.2.2/voro++/ directory; please check Voro++ documentation or read zeo++-0.2.2/voro++/README):
  4. cd zeo++-0.2.2/voro++/src
  5. Compile Zeo++ code:
  6. cd ../..
  7. Step (3) will create "network" binary inside zeo++-0.2.2 directory. This is the main Zeo++ binary. Please view Examples pages for a crash-course on using Zeo++. Details of the code are available on Documentation pages. A short help page is displayed when Zeo++ is executed without parameters:
  8. ./network


If you find this software useful, please contact me, as hearing back from people greatly helps in the development of the code. I am very interested to hear of additional features that people would find useful that Zeo++ currently does not support.


If you plan to publish an academic paper using this software, please consider citing the following publication

The first reference is the main Zeo++ reference describing the idea of using Voronoi networks in analysis of porous materials. The second reference describes extensions allowing sampling of structures from a database of porous materials using divrsity-based selection.
