Particle Based Methods
The discrete element method (DEM), also called distinct element method, based on spherical and cylindrical particles, it is widely recognized as a suitable tool to model geomaterials, advantages of this method are clearly seen in modelling problems characterized with strong discontinuities like rock fracturing during excavation. The discrete element model assumes that material can be represented by an assembly of rigid particles interacting among themselves. The overall behaviour of the system is determined by the cohesive/frictional contact laws. The contact law can be seen as the formulation of the material model on the microscopic level. Cohesive bonds can be broken, which allows us to simulate fracture of material and its propagation.
GiD support completely these kind of methods with a circle and sphere mesh generator, as well as specific visualization features totally suited to the requirements of them, which imply the management of a large number of particles.
GiD is ideal to be used in a multi-user environment in universities, research centers and enterprises for development and applications of different numerical simulation programs.
