Parallel computation methods for large-scale nonlinear CSM

Publisher Summary In this chapter, a parallel explicit dynamic finite element code, “ParaAble”, is used for the three-dimensional analysis of penetration and blast loading events. The analysis of structures undergoing complex inelastic responses to load—such as those resulting from explosive detonations or high-speed impact—are challenging mechanics problems, which can typically require significant computational resources. The analyses presented in the chapter involve large models (up to several million elements) and different types of material models with varying levels of complexity and computational expense. The parallel computational strategy includes an overlapping computation/message passing algorithm and a material-weighting mesh partitioning scheme. These procedures are implemented into a parallel finite element code, “ParaAble”, and then it is used for several large-scale applications.
