This is a research topic in itself, if you ask. Personnaly, I don't know how to scale the model adequately for debris transport problems, and I suspect nobody knows...The mean radius of the debris is about 0.0004 m, in this case the critical timestep is 10^-6 and with many particles it takes too much time to have a one or two minutes simulation, in Your opinion could I use a scaled model to have a bigger radius ad a bigger timestep, how should I modify set up parameters like Gravity, should I leave 9.81 cause the mass is auto calculated from dimensions? Of course all the force in action would be very much larger loosing the adherence to reality and some potential useful informations, from the point of view of particle motion, this scaling would change the final result, in the sense that i would like to see how particles moves to improve design.
As Vaçlav replied already : it would be enough to choose (or write) a contact law with a tensile strenght. Then all you need is to set the tensile strength value using Python interface. Be carefull about "links" if you think "permanent links". The "link" concept is being removed from Yade slowly, we only have "interactions" now.How can I set particle links with python script, there is a function that at a certain level of force breack the links?
