please help to solve the error.

Hello everyone , i want to add the region command to the fix efield i did modify the .h and .cpp files in src folder but i still can not use an electrostatic field in a specified region with at an angle needed for my simulations i hope you can help me and thanks

this is the .h code

#ifdef FIX_CLASS

FixStyle(efield,FixEfield)

#else

#ifndef LMP_FIX_EFIELD_H
#define LMP_FIX_EFIELD_H

#include "fix.h"

namespace LAMMPS_NS {

Hello Team, Greetings. I'm working on an homogeneous simple shear simulation using "fix Deform" method in LIGGGHTS.

Hi

Can anyone please tell me that is it possible to compile the makefile of liggghts as parallel with VTK installed as serial?

Thanks and regards

Hello everyone,

I am calling the Voronoi compute in pair_gran_base.h to use for some pressure computation.

// setup voronoi info
Compute *voronoi_info;
char id_voro[] = "voroinfo";
int icompute = modify->find_compute(id_voro);
if (icompute < 0)
error->all(FLERR,"Could not find voro compute ID");
voronoi_info = modify->compute[icompute];

Then I just add "compute voroinfo all voronoi/atom" into the .in file

It is all good at this moment.

I would be really happy that any of you share a triaxial code with me as I am beginner in this field.
I have already wrote this code :

Hello,
I am trying to run a simulation where particles released freely from a height of 700 µm, due to gravitational and contact forces, these released powders freely deposited into the box and formed a powder bed. A roller is then applied to spread a 50 µm high layer of metal particles.
Can anyone share a code for that ? With which tutorials I can start or modify it or which command I should use ?
I am actually a total beginner. I would be glad if anyone can help through with the steps involved in the simulation.
thnx.

Hello,
(Edit : Moved to liggghts users forum)
My simulations have been hanging when running them on several nodes. They work fine in a single node with several cpus. I was able to get a Minimal Working Example based on the packing example. Just by adding a single line
write_dump all custom out/dump_initial.gz id

Hello friends, I created an array in hooke model to dump vdw force components. The values are accumulating over time. Let us say, I have two particles that are coming closer, colliding, and moving away in 10 steps. Here are a few details.

step fvdw fc
1 0 0
2 0 0
3 non-zero 0
4 non-zero non-zero // Collision
5 non-zero non-zero // Collision
6 non-zero non-zero // Collision
7 non-zero 0
8 non-zero 0
9 non-zero 0
10 0 0

Hi,
I am working with liggghts to simulate the motion of a number of particles in a defined block. I have obtained some results for that, but I wanna see the initial condition effect on my result. To this end, I have changed the seed number in my insertion command
