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.

Developed with ease of use in mind, everyone is able to set up and perform complex multiphysics simulations in a simple GUI without learning any coding, programming, or scripting. Collecting results scattered in the literature, MATLAB® and C Programming for Trefftz Finite Element Methods provides the detailed MATLAB ® and C programming processes in applications of the Trefftz FEM to potential and elastic problems. Learn how to perform 3D finite element analysis (FEA) in MATLAB. This can help you to perform high-fidelity modeling for applications such as structural mechanics, electrostatics, magnetostatics, conduction, heat transfer, and diffusion. This webinar demonstrates the workflow steps for 3D FEA in MATLAB: 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. You can use this argument with any of the previous syntaxes.
