An OpenMP Application for programming with Element By Element Storage in Finite Elements Analysis
Abstract
This article aims to present the solver algorithm, which solves the system of linear equations generated by the Finite Element Method and evaluates its efficiency using a code that analyzes the behavior of a rock mass when a tunnel is excavated. The algorithm was developed for a shared memory platform as it uses the Preconditioned Conjugate Gradient Method paralleled with the OpenMP interface. It was used Element by Element Storage Strategy. A comparison was made between the developed algorithm and another that is sequential and uses the Gaussian Elimination Method, associated with the skyline storage technique. It was found that the developed algorithm was 84.07% faster.
