Author(s): Chen, Long | Abstract: We discuss how to implement the linear finite element method for solving the Poisson equation. We begin with the data structure to represent the triangulation and boundary conditions, introduce the sparse matrix, and then discuss the assembling process. We pay special attention to an efficient programming style using sparse matrices in MATLAB.

FEATool Multiphysics MATLAB FEM Toolbox FEATool Multiphysics (https://www.featool.com) is a fully integrated, flexible and easy to use physi FEM = assembleFEMatrices(___,state) assembles finite element matrices using the input time or solution specified in the state structure array. The function uses the time field of the structure for time-dependent models and the solution field u for nonlinear models. As for any other numerical method, the application of the FEM is linked to the programming language and software tools chosen. Historically the first programming language for practical use of the FEM was FORTRAN.

This book is a must for people who want to understand the finite element method and for people who want to learn how to program it using 'Matlab'.

The purpose of this chapter is to learn how to program the finite element method (FEM) in Matlab. The basic structure of a general finite element program normally consists of three main parts as PROGRAMMING OF FINITE ELEMENT METHODS IN MATLAB 3 computer memory by not storing many zero entries. We refer to the book [6] for detailed description on sparse matrix data structure and [7] for a quick introduction on popular data structures of sparse matrix. In particular, the sparse matrix data structure and operations FEM-in-MATLAB This is a training program in finite element method in matlab.

FEATool is an easy to use MATLAB Finite Element FEM toolbox for simulation of structural mechanics, heat transfer, CFD, and multiphysics engineering

% This is a simple 1D FEM program. The FEM % solution is based on linear elements also called hat functions.The % problem addressed is the extension of a bar under the action of applied % forces. Use mesh parameters under the heading mesh of this code to change % values. For example change the number of nodes to 2 to really see the % difference between the exact and the FEM solution.

FEATool Multiphysics MATLAB FEM Toolbox FEATool Multiphysics (https://www.featool.com) is a fully integrated, flexible and easy to use physi In MATLAB, B = zeros (m, n) creates m ń matrix B of zeros. A random m ń matrix can be created by rand (m,n).In finite element method, matrices are often sparse, i.e., they contain many zeros. MATLAB has the ability to store and manipulate sparse matrices, which greatly increases its usefulness for realistic problems.
