samadii/dem
generalized DEM(Discrete Element Method) solver
Generally speaking, there exist various types of solid particles in the industrial fields such as: in terms
of particle-scale, from Nano-sized particles
which cause a defect in the semiconductor process, virus, micron-particles which are used in the
printer-toner, chemical by-products, ultra-fine powder in
the grinding process, sand, gravel, grains, and mineral ores.
Discrete element method(DEM), also called as distinct element method, is a kind of analytical method
which recognizes interactions between various
types of solid particles; predicts the motion of large number of small particles or efficiency of the
combination of more than two types of particles;
or pre-measures the external forces on structures applied by particles. In other words, it is a Lagrangian
method which determines the movement by using
the six degrees of freedom motion equations and considers all forces of individual particles; and it uses to
receive the time integration with explicit method.
Therefore, DEM requires a lot of memory and computing power for its very small time step and large
number of particles to be considered generally.
samadii/dem, which is designed to perform analysis based on the GPU and parallel processing
techniques, provides highly reliable analysis results
by analyzing a variety of large-scale grain boundary issues at a high speed.
