The Discrete Element Method (DEM) is a numerical method to compute the dynamics of particles. Widely accepted as a good approach for solving problems related to discontinuous materials, its development and use is growing rapidly thanks to the advance in computer hardware. The increasing speed of processors, access to memory and specially the parallel computing, together with an actual discontinuous solution for discontinuum problems are the main reasons why particle methods are becoming more and more popular.

DEMPack is the name of a family of DEM -based software products. The DEMPack Team was created in 2012 in CIMNE (www.cimne.com ) and is in charge of all these products. The programming work is being done within the framework of the open source code Kratos Multiphysics ( www.cimne.com/kratos ), so all possible couplings with fluids, structures, and electro-magnetism, can be done easily in the same framework. DEMPack has adopted the Kratos philosophy of ensuring parallelism in every computation.
The main results of the DEMPack work consist on:
Using the DEM technology, CIMNE has developed a multipurpose and versatile code capable of tackling with a wide range of engineering and science problems. The code is multi-platform and takes advantage of the latest developments of the community regarding parallel computing. The list of problems the DEMPack software is capable of studying includes the following:
1. Granular Flows
