An algorithm for domain decomposition in finite element analysis
Moayyad Al-Nasra,Duc T. Nguyen +1 more
TL;DR: A simple and efficient algorithm is described for automatic decomposition of an arbitrary finite element domain into a specified number of subdomains for finite element and substructuring analysis in a multi-processor computer environment.
Proceedings ArticleDOI
A parallel-vector algorithm for rapid structural analysis on high-performance computers
TL;DR: In this article, a fast, accurate Choleski method for the solution of symmetric systems of linear equations is presented, which is based on a variable-band storage scheme and takes advantage of column heights to reduce the number of operations in the choleski factorization.
Journal ArticleDOI
Parallel-vector solution of large-scale structural analysis problems on supercomputers
TL;DR: This direct method is based on the Choleski factorization procedure and uses a skyline storage scheme and unique features of the method include its parallel computation at the outermost DO-loop and vector computations at the innermostDO-loop.
Journal ArticleDOI
A FE model updating technique based on SAP2000-OAPI and enhanced SOS algorithm for damage assessment of full-scale structures
TL;DR: A FE model updating technique based on the existing commercial software SAP2000-OAPI and an enhanced symbiotic organisms search (ESOS) algorithm for damage assessment of full-scale structures and the feasibility of the proposed technique in predicting the actual damage sites and their severities is demonstrated.
