Dynamic Fracture Analysis Using an Uncoupled Arbitrary Lagrangian Eulerian Finite Element Formulation

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

Development of a Scalable PIC Simulator and Its Application to Spacecraft–Plasma Interaction Problems

The particle-in-cell (PIC) method is widely used for various problems in space plasma physics. Spacecraft-plasma interaction problem is one of such extensive topics. With increasing space development and exploration, a strong demand should arise regarding better understanding of plasma disturbance around a spacecraft. For the study, we have developed an electromagnetic PIC code EMSES [1] for th...

Dynamic Load Balancing for Adaptive Scientific Computations via Hypergraph Repartitioning

Adaptive scientific computations require that periodic repartitioning (load balancing) occur dynamically to maintain load balance. Hypergraph partitioning is a successful model for minimizing communication volume in scientific computations, and partitioning software for the static case is widely available. In this paper, we present a new hypergraph model for the dynamic case, where we minimize ...

Implementation of a 2D Electrostatic Particle in Cell algorithm in Uni ed Parallel C with dynamic load-balancing

Since space plasmas are colisionless, reliable space weather simulations will require to take into account a full kinetic description of their dynamics. The Particle in Cell (PIC) method is a particle-mesh technique that e ciently allows such description. Still, realistic plasma simulations require huge data sets and are computationally expensive. High scalability must thus be achieved in order...

تحلیل دینامیکی سد‌های بتنی وزنی با مدلسازی مخزن به روش‌های لاگرانژی و اویلری

Because of different behavior of reservoir water and dam material, the determination of hydrodynamic pressure during earthquake is very complicated. Thus, different formulations have been presented for modeling of the dam reservoir system under dynamic loading such as earthquake. These formulations can be categorized into two general groups, which are Lagrangian and Eulerian, each having advant...
