Abstract:
Finite element analysis has been used successfully since the advent of computers to analyze complex engineering and physical systems. FEM modeling lacks a well-defined formal definition for composing new models from pre-defined sim-pler models. Building hierarchical models of engineering and physical systems out of simpler components provides great advantages in terms of testing, maintenance and reuse. In order to achieve these goals, we explored the use of Cell-DEVS as an alternative to model and solve problems that are usually tackled using the Finite Elements Method (FEM). We focus on an example about how to approach the problem definition using Cell-DEVS, which provides a base to extend this to more complex problems. It also compares results obtained with those obtained using FEM in order to highlight the advan-tages and disadvantages of the Cell-DEVS approach. We discuss the advantages of this approach to solving complex physical and engineering problems against the use
to be solved with finite elements or finite difference methods.
