Just a note: if you set the permeabilityFactor negative then the value is used
as a Darcy conductivity (probably not a perfect equality but very similar order
of magnitude).

This really depends on many parameters (compressibility of the fluid,
permeability of the porous medium, stiffn

Hello,
Maybe Bruno should answer this since he is one of the creators of yade's
PFV, but I might as well share my understanding of how it works. PFV
simulates a network of pore

Hi,
I don't understand the problem described.
The fact that the simulation does not match experiments says nothing, you need
to compare with a theoretical solution.

Hello Deng,
Just a thought, have you considered the permeability of the experimental
specimen vs the permeability of your numerical specimen[1]?
Cheers,

Dear all,
I'm trying to simulate a granular seabed under stationary wave pressure by
using DEM-PFV model.
But I have a problem when I try to varify my simulation result. I find that
