LIGGGHTS® - User Forum

Hi,
I am new to DEM and I have never used LIGGGHTS. Before I get started with the software, I was wondering if LIGGGHTS can simulate the packing of particles of various aspect ratio. If so, is there any tutorial on this type of simulation? My end goal is to predict packing porosity for a given particle size distribution of different aspect ratio. Please let me know if you have done something similar in the past. I would appreciate any input.

Thanks

Dear All

is it possible to install two different LIGGGHTS version together?

Hi,

for LIGGGHTS
Is there any acceleration method? (other than mpirun)
can we compile it by icc instead of g++? if it's possible, how to?!

Thanks in advance,

Hello all,

I am using compute_stress/atom class. I see the per atom stress is the pair_wise atom stress, not including the stress between the wall and the atom. Is there a simple method to achieve this function?

Thanks in advance.

Hello All,

I would like to test Liggghts. Is there a windows version available?

Thanks

Dear All

Is there any command to define "dynamic friction coefficient" between particles

I'm already working on a mill simulation and i'm trying to count the particles that come out of the mill. For this, i'm using the massflow/mesh command, however i have a problem with one of the keywords. Specifically, the vec_side command, because i don't know what it means this "vector components defining the "outside" of the mesh". My stl surface is in the 5.3,0,0 coordinates, but when compile the file, it doesn't count the particles.

Please, i need some help.

Best regards, Nicolás.

Dear all,

I am struggling with dump custom/vtk (3.2.0 and 3.3.0) that always results in an error: Invalid dump style (output.cpp: 591). I have not tried this command before. I usually use lpp to convert to vtk. An example of my using dump custom/vtk as below:

dump dmp all custom/vtk 10000 dump.liggghts_init id type type x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius

Thank for concern,

Regards,

Hi, All:

Hi vinaym,

by mistake (moving and deleting the old thread) I deleted your thread. I am sorry. Find below your original one and my answer.

Hello all,

I tried compiling latest version : LIGGGHTS® 3.2.0 (released 29 April 2015) with the optional packages ASPHERE and MOLECULE.

But I get the following error.
