Análise da viabilidade de modelagens numéricas em Softwares Open source

Abstract

The need to mathematically represent physical phenomena motivated the development of numerical methods along with the rise of computational processing capacity has become something with great applicability in physical engineering simulations. So, it was noticed the emergence of software development communities that soon became major reference institutions in the area of physical simulations. Consequently, there were important phenomena. First, commercial software has graphical interfaces that allows a great interaction with users, facilitating the stages of construction of a numerical modeling, however, hiding the need to understand the calculations involved. It is also noted, the high costs of implementing the software, given the complexity of the development. Therefore, this document aims to present the steps of numerical modeling in Open Source software evaluating and comparing with applications in commercial software. The openfoam multiphysics simulation platform was used to build a thermal modeling. Therefore, it was possible to describe the stages of numerical modeling compared to commercial modeling and the ability of the free software development community to present efficient tools was noted.
