It has been developed to improve the generation of unstructured 3D grid using the Voronoi method. Voro2Mesh allows a three-dimensional MESH generation letting the user to choose between several options to build the grid.

Get a free copy of VORO2MESH beta (fully functional) from the download page linked in the left menu panel and please send us your suggestions for further developments.

The software is still under development, therefore a feedback from you is very much appreciated, thank you.
