Hi all,

i'm trying to reproduce a rotary kiln with two different form of particles, rectangular and spherical,
my problem is that when I try to change the neighbor from nsq to bin it gives me a segmentation fault,
I've saw that the problem is probably related to the neighbor bin, which I have to select when I add triangular meshes. Someone knows how to solve this?

Regards,

Hi,

an updated tutorial for Ubuntu, Mint and other Debian based distributions. Since MPI support didn't work the old way and I don't need it at the moment, I left it, maybe someone can post the solution. I integrate jpg and png support for image dump, since I do animations in ParaView. I updated the Syntax-Highlighting for gedit by Philippe Seil for LIGGGHTS 3.0. The file is detached, his original post not longer on-line anymore.
It would be fine, if you give feedback and recommendations.

Paul

Hi all,

i have to simulate the breakage behavior of rectangular particles, and i was asking myself if this is possible with fix rigid and fix bond/break

Best regards,

Hi Christophe,
I am a new user of LIGGGHTS. I have two questions for you.
Is the corrected version of Fix command (that takes the overlaps into account) in the public version?

Where can i find the full list showing which feature is in public version and which is not?

thanks,

Hi everybody,

Hi guys.

I met a problem when I was compiling LIGGGHTS on my PC(i5-3470, memory 4G ). After checking the settings with "cfdemSysTest", I began "cfdemCompLIG", it went smoothly at first, but when compiling certain **.cpp file, the screen was frozen. After long time(about 20 minutes), this situation stopped and the compling process went on, but there was no lmp_fedora_fpic in the src directory after the compiling process finished. Does anyone meet the same problem? Is that because the hardware of my PC too low?

Hi,

I am trying to simulate a system with two type of particles, the firsts are rectanuglar, and the others are normal spherical particles. The problem is that when I put all particles in my system, only rectangular particles move.
Here is my script, i home someone could help

thank you in advance for your help

Hi All,

Could anyone please discuss the reasons that particles go out of domain during simulation? The volume could increase quickly if particles are not in the domain.

Thanks!

Dear Colleagues,
My simulation ended up with an erro:
Mesh elements have been lost (multi_node_mesh_parallel_I.h:613)

Does some one know what might be the reason? Thank you

Dear colleagues,

Recently I am repeating a same simulation with different cores (1-128 cores ) with our HPC.

I find two things that are strange to me:

1. When the number of the cores changes, the number of the particles that are created from the input script is different, the difference is not big (a few to ten particles).

Is this a bug of the liggghts or i set wrong parameters?
