Title: | On the solution of a finite element approximation of a linear obstacle plate problem | Authors: | Fernandes, Luís M. Figueiredo, Isabel N. Júdice, Joaquim J. |
Issue Date: | 2001 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 01-18 (2001) | Abstract: | In this paper the solution of a finite element approximation of a linear obstacle plate problem is investigated. A simple version of an interior point method and a block pivoting algorithm have been proposed for the solution of this problem. Special purpose implementations of these procedures are included and have been used in the solution of a set of test problems. The results of these experiences indicate that these procedures are quite efficient to deal with these instances and compare favourably with the path-following PATH and the active-set MINOS codes of the commercial GAMS collection. | URI: | https://hdl.handle.net/10316/11459 | Rights: | openAccess |
