Hi
I'm new using LIGGGHTS.
I'd like to simulate a sand glass with LIGGGHTS. It works quite good for now, but i need a usable value for my sand's friction.
fix m4 all property/global coefficientFriction peratomtypepair 1 ??
If i had a Ra value, would it be possible to assess or even to compute the friction of my sand? (see the SEM picture)
Or has someone experience in simulating sand and knows a usable value?
something else:
I'm looking now for about 1h to find out, what LIGGGHTS means. It's something like LAMMPS improved general granular.... simulation...?
Can someone help me?
Thanks!
Miro

I've found the acronym for LIGGHTS

Hi Miro,
Hi Miro,
obtaining the correct parameters for a simulation is a tough job, since you usually get them from tuning a simulation to behave like a lab-experiment.
As you can imagine this takes quite the effort.
I am sorry, but I don't have values at hand, but maybe someone else on the forum has estimates.
Cheers,
Josef
