Modelling and Numerical Simulation via Variational Calculus University of Sao Paulo

Course Overview

The finite element computational simulation methodology, starting with the variational formulation of the problem, allows students to quickly familiarize themselves with finite element theory, to solve complex partial differential equations, to implement their own customized software to simulate a specific physical phenomenon required in their research, and to learn the necessity and importance of the variational calculus. It is a different approach in relation to what is present in the current finite element computational simulation commercial software, which contains the implementation of the final discrete (matrix) formulation of a problem, thus limiting the physical phenomena (differential equations) that can be modeled only to those problems already implemented in the Software. In the new approach we start with the variational formulation, thus allowing more flexibility and generality in the computational simulation of the physical phenomena (partial differential equations).

Learning Achievement

The aim of this course is to teach the concepts of a finite element computational simulation methodology that allows starting from the variational formulation of the problem to solve partial differential equations. In this way, concepts will be explored on the finite element method, variational calculation, high order linear system solution techniques and other concepts involved in the method. As a tool will be used FENICS software (free license), which is a recent computational tool that follows the concept of modeling from the variational formulation.
