Subdomain cluster generation for domain decomposition methods using graph partitioning optimization

Dimos C. Charmpis, Manolis Papadrakakis

Balancing and dual domain decomposition methods (DDMs) comprise a family of efficient high performance solution approaches for a large number of problems in computational…

Discrete atomic and smeared continuum modelling for static analysis

Young W. Kwon

A computational technique was developed to model and simulate molecular or atomic behaviour of materials under static loads. Interatomic potential was used to maintain…

Use of genetic algorithm to design optimal neural network structure

Nursel Öztürk

In this research, neural network (NN) and genetic algorithm (GA) are used together to design optimal NN structure. The proposed approach combines the characteristics of GA…

On solving singular interface problems using the enriched partition‐of‐unity finite element methods

C.K. Lee, X. Liu, S.C. Fan

It has been well recognized that interface problems often contain strong singularities which make conventional numerical approaches such as uniform h‐ or p‐version of…

Refinement of the convective boundedness criterion of Gaskell and Lau

Hou Ping‐Li, Tao Wen‐Quan, Yu Mao‐Zheng

Based on the normalized variable diagram, the weakness of the Gaskell and Lau's convective boundedness criterion (GL‐CBC) is revealed by numerical example. By careful…

Layout optimization of large‐scale pin‐jointed frames

Matthew Gilbert, Andrew Tyas

Computerized layout (or “topology”) optimization was pioneered almost four decades back. However, despite dramatic increases in available computer power and the…

Interprocessor communication schemes in parallel finite‐discrete element analysis on PC clusters

F. Wang, Y.T. Feng, D.R.J. Owen

Some issues related to effective parallel implementation of the combined finite‐discrete element approach on PC clusters are discussed. Attention is focused on the…
