LIGGGHTS® - User Forum

Hello everyone,

from my first attemts i think liggghts is a very nice simulation environment for high numbers of particles. However i have some questions.

1) What programs do you suggest for designing the complex walls ? (open source would be best)

2) Is there a way or is it planned to create a way to generate data about the stress/strain situation for each particle?

regards,
Martin Koester

Hi, Christoph,

Thanks for the help with running the LIGGGHTS examples.

After I ran the movingMeshGran and meshGran examples successfully, I tried to run the pour example in the lammps/examples folder (I included the granular package when I compiled lammps/LIGGGHTS). This example failed to run. I then installed the official lammps on another computer with the granular package included. The pour example ran without any problem. In the LIGGGHTS-beta version, is there a conflict between LIGGHTS and lammps?

Below are the error messages:

Dear LIGGGHTS group,

I managed to compile LIGGGHTS and pizza.py on OpenSUSE 11.2 64 OS with mpich2.

The first example I ran is the movingMeshGran example. This case created quite a few new stl files (dump###.stl). I will assume that these stl files corresponds to each time step. How to animate the stl files together with the particles? I can animate the particle motion in paraview, but, I do not under what the particles are doing. I guess I will need the stl geometries to understand.

Your assistance will be highly appreciated.

looking forward to the CFD-DEM code
