I am attempting to model a direct shear box test of sand with randomly distributed fibres. I will be looking at several fibre percentages by weight.

I would like to used chained cylinders to model the fibers however I am not sure the best way to simulate random distribution and orientation within the sample. I am looking at the chained-cylinder-roots.py example and it seems that the additional chains are just copies with the same alignment for small offsets. 

do you have any suggestions on how to achieve a more randomised distribution.

is it possible to model a single chained cylinder and add it using makeClumpCloud with a random orientation? 

thank you 
 
regards
Michael
