摘      要：Parallel computing is a promising approach to alleviate the computational demand in conducting large-scale finite element *** paper presents a numerical modeling approach for earthquake ground response and liquefaction using the parallel nonlinear finite element program,ParCYCLIC,designed for distributed-memory message-passing parallel computer *** ParCYCLIC,finite elements are employed within an incremental plasticity,coupled solid-fluid formulation,A constitutive model calibrated by physical tests represents the salient characteristics of sand liquefaction and associated accumulation of shear *** elements of the computational strategy employed in ParCYCLIC include the development of a parallel sparse direct solver,the deployment of an automatic domain decomposer,and the use of the Multilevel Nested Dissection algorithm for ordering of the finite element *** results of centrifuge test models using ParCYCLIC are *** results from grid models and geotechnical simulations show that ParCYCLIC is efficiently scalable to a large number of processors.
