Abstract
The Finite Element Method (FEM) is a way of numerical solution applied in different areas, as simulations used in studies to improve cardiac ablation procedures. For this purpose, the meshes should have the same size and histological features of the focused structures. Some methods and tools used to generate tetrahedral meshes are limited mainly by the use conditions. In this paper, the integration of Open Source Softwares is presented as an alternative to solid modeling and automatic mesh generation. To demonstrate its efficiency, the cardiac structures were considered as a first application context: atriums, ventricles, valves, arteries and pericardium. The proposed method is feasible to obtain refined meshes in an acceptable time and with the required quality for simulations using FEM.

Studies using the Finite Element Method (FEM) may be used to improve cardiac ablation procedure, such as radiofrequency cardiac ablation, and reduce possible complications

Summary
Studies using the Finite Element Method (FEM) may be used to improve cardiac ablation procedure, such as radiofrequency cardiac ablation, and reduce possible complications. The focus of the problem is monitoring the temperatures of the tissues and FEM simulations have contributed significantly to the improvement of this technique [2, 3, 4]. For such simulations, the finite element meshes should consider the anatomical and histological features of the target structures and its quality has to be acceptable. Some methods or tools used to generate meshes of biological structures are still limited by constructing non-detailed models or due to limitation in the use condition [2, 4, 5]
