Hey guys, I have done compression testing of particles in LIGGGHTS in 3D. Now, I want to do the same test in 2D. As per the documentation, I added command "dimensions 3" but I am getting an error while using "insert/rate/region" command and if I use "create_atoms" command by using the lattice for 2D, atoms are created, but the moment my wall touches the atoms, I get a message " Proc 0 Internal error", also in create atoms i am not able to add gravity. So, what is the correct procedure to model a simulation in 2D ?? and which visualization software is best to view it ??
Please help.
I am also sending this youtube link, which demonstrates 2D simulation. This is pretty much what I want.

Hi Anand M,
Hi Anand M,
many features in LIGGGHTS will not work in 3D because: no one here deems is worthy enough to put extra effort in implementing something in 2D which is actually removing physics from the system!
I would suggest you use a narrow 3D slot.
Best wishes

Creating annular region
Hey
Is it possible to create an annular region in LIGGGHTS ? In my problem I require the particles in a particular annular region to be dumped separately.
How to use the intersect or union command to go about doing this ? Please help
regards
Anand
