Parallel Finite Element Modeling of Earthquake Ground Response and Liquefaction

Parallel computing is a promising approach to alleviate the computational demand in conducting largescale finite element analyses. This paper presents a numerical modeling approach for earthquake ground response and liquefaction using the parallel nonlinear finite element program, ParCYCLIC, which is designed for distributed-memory message-passing parallel computer systems. In ParCYCLIC, finite...

Simulation of Earthquake Liquefaction Response on Parallel Computers

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 develo...
