SUMMARY:Discontinuous Numerical Methods and High-Performance Computing for
  Geotechnical Engineering
DESCRIPTION:Minisymposium\n\nNumerical simulation has become a necessary t
 ool in the field of geotechnical engineering. As the common material invol
 ved, geomaterial is always with great discontinuity, heterogeneity, and an
 isotropy. To describe the mechanical behavior of geomaterial, various comp
 utational methods have been developed. As an important branch, discontinuo
 us numerical methods are designed using the bottom-to-top strategy, in whi
 ch the computational model is divided into a group of discrete elements to
  reproduce the response of its physical counterpart. Compared to continuou
 s methods, such as the finite element method (FEM), the discontinuous nume
 rical method is regarded as superior in representing characteristics of ge
 omaterial and obtaining closer results to those of laboratory testing. How
 ever, they are always handicapped to be further applied into the practical
  case in geotechnical engineering due to the extra high computational requ
 irements, e.g., over millions if not billions of numerical elements are ge
 nerally required for discontinuous numerical model of a large scale slope 
 or underground cavern. This mini-symposium targets presenting new parallel
  computing algorithms of discontinuous numerical methods for geotechnical 
 engineering, including but not limited to new developed computing methods 
 such as the discontinuous deformation analysis, the discrete element model
  and the four-dimensional lattice spring model.\n\nMatrix Computing of Mul

 Method\n\nLiu, Zhu\n\nBased on the traditional pore network model and the 
 discrete element method, a pore density flow method is introduced, which c
