چکیده
This paper presents a parallel nonlinear finite element program, ParCYCLIC, which is designed for the analysis of cyclic seismically-induced liquefaction problems. Key elements of the computational strategy employed in ParCYCLIC include the deployment of an automatic domain decomposer, the use of the multilevel nested dissection algorithm for the ordering of finite element nodes, and the development of a parallel sparse direct solver. Simulation results of grid models and a centrifuge test model using ParCYCLIC are presented. Performance results show that ParCYCLIC is efficiently scalable to a large number of processors.
