Szemcsés anyagok nyírása – running

We would like to study the shearing of anisotropic granular materials using molecular dynamics. During the last two years we successfully extended the LAMMPS molecular dynamics code to incorporate breakable glued contacts (Gran. Mat. 13/777 2011). Using this code we could already simulate elongated particles by gluing spheres together (Phys. Rev. Lett. 108/228302 2012). This is however very resource intensive calculation as we glue 5-10 spheres together and also bigger sample are needed to get rid of boundary effects.

The LAMMPS simulation code is prepared to run efficiently on parallel systems and in purpose made parallel environments the CPU usage scales linearly. Therefore the supercomputer of the BME is an ideal environment for our studies.

The actual project concentrates on the validation of a mesoscopic model.
