Lethe DEM
Lethe-DEM is an Open-source fully-parallel Discrete Element Method (DEM) Software. Lethe-DEM contains two-dimensional (dem_2d) and three-dimensional (dem_3d) solvers, and is based on the deal.II open source framework (https://github.com/dealii/dealii).
Lethe-DEM is intrinsically rely on a background mesh defined using deal.II. Lethe-DEM is fully-parallel and capable of load-balancing. In load-balancing, the computational load (mainly due to number of particles on each processor) is redistributed during a simulation. Lethe-DEM supports Hookean (linear viscoelastic) and Hertzian (non-linear viscoelastic) contact force models. It is still an immature project, but is under active development.
Note: Lethe-DEM would not exist without the thorough dedicated work of the deal.II authors. The authors of Lethe would like to emphasize that without deal.II, dedicated solvers like Lethe could not exist.
- Lethe-DEM solvers are automatically installed by installing Lethe
- Lethe-DEM can be installed on Linux either on a dedicated machine or on a virtual machine
- Lethe-DEM has been tested on numerous distributions, including Ubuntu 18.04 LTS and Centos 7
