Re: Python scripting for create links, change player config and model scale question


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.

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...

How can I set particle links with python script, there is a function
that at a certain level of force breack the links?

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.
