Re: [Question #237037]: Porosity control (fixed volume and particle size)

 

Question #237037 on Yade changed:

Bruno Chareyre proposed the following answer:
The triaxial engine doesn't care about what type of contact laws you
use. It should be ok with viscoElastic contacts. But graviational is ok
as well, no need to tackle all problems at once.
One way to compute porosity when the geometry is complex (a free
surface, for instance), is to use TesselationWrapper [1], then you get a
porosity per particle.
You can average this data in inner regions to get the average porosity.

It would probably be interesting to use this also for the flow, since it
would give for instance porosity vs. height inside the flowing material,
or porosity change along the slope.
