Re: [Question #689293]: Simple PFV case


Question #689293 on Yade changed:

    Status: Open => Answered

Robert Caulk proposed the following answer:
The infinite K1 warning is just that, a warning.

If you have a regular packing like I assume you do here, the voronoi
centers of cells may end up directly on top of one another, which is not
a problem for triangulation, but is a problem for estimating
permeability inversely proportional to distance between voronoi
centers...thus the warning. Yade puts an arbitrarily high permeability
between those cells.

The best reference is [1][2].
