Hi Dear Jan

Thanks again for your support. 
Q. Do you have / is it easy to create some "patch test", simple analytical
solution to test the implementation? Something like interaction of two
particles and particle to fibre, with a few different orientations.

A. Yes we can do this. However, I think it is better to initially solve
easier form of our problem (i.e., modelling dry soil without fibres'
contribution) and once it is verified with Yade platform then we can add
to it to include the effect of fibres. What is the maximum number of
particles that can be used in Yade? Assuming that clay particles are
very small and a small sample of 50mm (dia.) and 100mm(height) will
include millions of particles. Perhaps we can bond some particles
together to create agglomerates. However, the other issue is the
relative size of the fibres compared to clay particles as they can
connect two particles or hundreds of particles.

Q. What do the forces between particles depend on? Apart from material
properties, it should be only distance.. Does it fit your assumptions?

A. Yes distance as well as gravity

Q. Concerning forces, could you please try to describe what you would like
to achieve? Some equations, assumptions, how far the forces are supposed to
act (relatively to the clay particle size), what they depend on etc. etc.

A. Our main problem is to modeling the fibres as a particles with random
distribution inside the soil particles and consider their interaction
(i.e., non-homogeneous, anisotropic media).

Q. Have you used / tested Yade before? It needs Linux, uses Python (so you
need at least some Python scripting knowledge even for the very basic
usage) etc...
- what operating system do you use?
- anything else you feel is relevant..

We have Yade installed on UBUNTU and we are familiar with Python
scripting.

Here is a picture of the soil sample we use (this sample has been sheared and it's been dried)
