Simulation is an important tool for the study of real situations, or predictions about various situations. Therefore seeking to obtain the influence of the parameters in the simulation, this work was done to approach the mesh characteristics, simulation of a cantilever. Ansys® the software was used to study the parameters. For the experiments, approach issues such as finite element analysis, tensile and flexural strength, and strain gage and simulation was needed. Through some experiments with the tensile test and scanning electron microscope of aluminum bar, the mechanical properties and chemical composition were obtained. The cantilever was analyzed with extensometer for strain variation, upon application of load. With the variation of the mesh parameters, simulation was done of the cantilever and the results were compared to those obtained with strain gauge. It was observed that the simulated values are very close to the real and the ideal refinement was given a point.
