Estudo e Análise de Processamento Paralelo em Simulações de Fluidodinâmica Computacional com OpenFOAM
Abstract
This papers aims to analyze the performance of parallel methods implemented in the computational fluid-dynamic tool, OpenFOAM. This analysis is based on two cases in different contexts and complexities. The results shows that the considered parallel methods of the tool do not scale and specific efforts to adjust input parameters are necessary for convergence in complex cases.
