Hi,

While installing LIGGGHTS on HPC error comes up saying
Unable to locate shared libraries libvtk commomcore.so....... # loaded only openmpi module

I doubt this is because of missing libraries like paraview-openmpi paraview-openmpi-devel
The person who is installing has asked me to send the links for these libraries.
I am unable to find the packages. Can you help me in this regard?

Regards,
Shiva.

Dear all,

Hi everyone,

I am trying to to install the python interface to LIGGGHTS and it does not work when I use the auto makefile.

I have three computers with LIGGGHTS installed. For tow of them I modified and used the ubuntuVTK6 makefile and compiled LIGGGHTS as normal. It worked, so I then compiled LIGGGHTS as shared libraries following the instructions and it worked as well.

In the third computer I used the auto makefile for the normal compilation, and it worked. However as I tried to compile LIGGGHTS as a shared library, it does not work.

hi,

Recently I got access to HPC which runs on REDHAT
I have an executable file lmp_auto, loaded to my login node using sftp.
From the available modules I loaded openmpi-1.6.4,fftw & hdf5 libraries and submitted the job.
Below is the script file

#! /bin/csh
#PBS -l walltime=01:00:00
#PBS -N hopper
#PBS -q workq
#PBS -l select=4:ncpus=16:mpiprocs=16
#PBS -l place=scatter:excl
#PBS -V

# Go to the directory from which you submitted the job

cd /scratch/shiva/hpc1

module load openmpi-1.6.4

Hi everyone,

I am trying to build LIGGGHTS 3.7 on the Raijin cluster at NCI in Aus. LIGGGHTS-3.6 is already installed on the cluster, but I am aiming to install and use CFDEM as I have on the Uni cluster (which is being decommissioned next month, hence moving to Raijin).

The cluster already has VTK 6.3 installed, however I have decided initially to compile without VTK by altering the Makefiles I use, removing -DLAMMPS_VTK and the VTK library and include locations.

Hello everyone

Can anyone give me the syntax for creating spherical particles in range from 50e-6 to 100e-6 in liggghts 3.7.0

Thank you in advance

Hello everybody,
I'm trying to run an example of cohesive force model of washino/capillary/viscous. When I run this script (as below) the memory usage of the computer is increased illogically so that the run is dead. I decreased the amount of particles but it doesn't solve the problem. May you please help me to know what's the reason and what I can do to fix it?
Thank you

the input script is:

#Contact model example

atom_style granular
atom_modify map array

boundary m m m
newton off

communicate single vel yes

units si

Hey,

I got a question about implementating a value in CFDEM Ligghts.

How do I implement a time-variable value, which shall be variable at every time step?

Is this a possible way to realize my question?
Csurface = fix_Csurface --> vector_atom
vector_atom = Csurface
fix_Csurface = NULL

Thanks for your helpful minds :)

Hello everybody,

I want to simulate a belt conveyor which also rotates around a defined axis.
Normaly I used this command to give the surface of the belt velocity components

fix cv1 all mesh/surface/stress file belt_1.stl type 3 scale 0.001 surface_vel ${beltvX} ${beltvY} ${beltvZ}

Then I want ro rotate this mesh with following command

fix rotatecv1 all move/mesh mesh cv1 rotate origin 0.0 698.8 0.0 axis 0.0 0.0 1.0 period ${time1}

Dear all,
hello,
I'm new on LIGGGHTS so please forgive me if the question is stupid.
I was running the cohesive example of LIGGGHTS. When I changed the cohesive force as washino/capillary/viscous I received this error: "ERROR: Could not locate a fix/property storing value(s) for surfaceLiquidContentInitial as requested by cohesion_model washino/capillary/viscous. (../modify_liggghts.cpp:411)"

could you please help me to fix this?
Thank you in advance

the in.cohesion file is as:
