Hexahedral elements are also available on a limited basis in recent releases of CATIA.

In general, the analysis of bulky objects requires the use of solid elements. Another important feature of parabolic elements is that they can fit curved surfaces better. On the other hand, the parabolic elements require more computational resources but lead to more accurate results. The linear tetrahedron elements are faster computationally but less accurate. Both are referred to as tetrahedron elements and shown below. There are two main types of solid elements available in CATIA V5, linear and parabolic. Although this problem is more efficiently handled with beam elements, we propose to use solid elements. The nominal dimensions of the rod are also displayed below. The steel rod has a Youngs modulus of 30E+6 psi and Poisson ratio 0.3. 1 Problem Statement The bent rod, shown to the right, is clamped at one end and subjected to a load of 2000 lb as displayed. Finally, the significance of the von Mises stress in design equation is discussed. No planes of symmetry exist and therefore model simplifications cannot be made. Introduction In this tutorial, a solid FEA model of a bent rod experiencing a combined load is created.

The tutorials are based on release 21 however, other releases can also be used with minor changes.

However, it is assumed that the user is familiar with CATIA V5 Release 21 interface and basic utilities such as pan, zoom, and rotation.

The reason behind the simplicity is not to burden the reader with the CAD aspects of the package. In this workbook, the parts created in CATIA are simple enough they can be modeled with minimal knowledge of this powerful software. However, the best strategy to learn is to sequentially cover the chapters. The chapters are designed to be independent of each other allowing the user to pick specific topics without the need to go through the previous chapters. The objective of this tutorial book is to expose the reader to the basic FEA capabilities in CATIA V5 Release 21. Intended for people already familiar with the basics of using CATIA.Each chapter is completely independent of each other.Covers a wide variety of problems using step by step tutorials.Introduces new users to the Finite Element Analysis capabilities of CATIA 21.
