Dear All,

I am working in the field of Discrete Element modelling of masonry structures by means of 3DEC software and would like to mesh my blocks by means of a Voronoi taxellation, to get more realistic crack progression. I am, however, not satisfied by the Voronoi meshing commands in 3DEC, as the mesh is often too coarse.

Let's say I am generating solid, parallelepiped blocks through Rhino. How would you suggest meshing them, later on, to get a Voronoi mesh both on the surface and the inside of the block?
