Manuscript Title: ppohDEM: Computational Performance for Open Source Code of the Discrete Element Method
Authors: Daisuke Nishiura, Miki Y. Matsuo, Hide Sakaguchi
Program title: ppohDEM
Catalogue identifier: AESI_v1_0
Distribution format: tar.gz
Journal reference: Comput. Phys. Commun. 185(2014)1486
Programming language: Fortran.
Computer: CPU based workstations and parallel computers.
Operating system: Linux, Windows.
Has the code been vectorised or parallelized?: Yes, using MPI. Tested with up to 8 processors.
RAM: Dependent upon the numbers of particles and contact particle pairs (1GB for the example program supplied with the package)
Keywords: DEM, Particle, Collision, Parallel computing.
Classification: 6.5, 13.

External routines: MPI-2, OpenMP

Nature of problem:
Collision dynamics of viscoelastic particles with friction in powder engineering and soil mechanics.

Solution method:
Parallelized DEM running on shared and/or distributed systems is the solution method based particle model in which geometrical size and shape attributes are provided for each element. In the DEM, the Voigt model and Coulomb friction model are considered at each contact point between particles.

Running time:
10 minutes for the example program supplied with the package using 2 CPU (each with 10 cores) of Intel Xeon E7-4870.
