Is it possible to do tessellation on clumps packing

Asked by ceguo

Hi,

I notice YADE can do both Voronoi and Delaunay tessellations for spherical particles. However, if I use clumps (simple ones, like two particle-clump to approximate ellipsoids), is it possible to do these two tessellations in YADE?

Thanks in advance.

The triangulation module actually uses "regular" triangulation, not Delaunay. I possibly typed "regular Delaunay" here and there in the documentation, but it was a mistake (if so, let me know where you found the name Delaunay)
Regular tesselation is defined as long as one sphere does not include the center of another sphere. So, they can overlap but not too much. In this condition, you can tesselate clumps. Most values will be wrong however. Compute porosity for instance, could well be negative since the solid volume will be the sums of clumps members volumes.

Can you help with this problem?
