Figure P Figure P NOTES: Placed Features, Assembly Modeling Techniques Chapter 3 Modeling Techniques OVERVIEW This Chapter discusses modeling techniques that illustrate the flexibility inherent in the feature-based parametric modeling of DesignModeler. In parametric design modeling we wish to assign parameters to these quantities so that they can be varied to fit various design requirements. It is also possible to write equations that relate the required variation in certain parameters in terms of other parameters. For example, it might be important for a hole always to be centered in a bracket even if different designs require that the bracket width change with application. Tutorial 3A illustrates this use of parameters. DesignModeler is a full-featured parametric design modeling system that provides for importation of models from other CAD systems and also allows the user to export models to other CAD systems.

One vehicle for doing this is the use of the standard neutral file formats IGES Initial Graphics Exchange Specification and STEP Standard for the Exchange of Product Model Data , agreed upon standards for the transfer of models between systems. Modeling Techniques Parts in DesignModeler are composed of Bodies whereas Assemblies may be composed of Parts. We illustrate these concepts also in this Chapter. The part in question is shown in the figure below. Here we wish the long leg of the bracket always to be 1. The bracket thickness is to be constant. These invariant design requirements are accomplished using parametric relations in Designlvlodeler, 1.

iges or STEP SURFACE AND LINE MODELS Surface models are necessary if one wishes to perform analysis using simplified planar or 3D surface models instead of solids. Line models are needed when line elements are being used in engineering truss or beam simulations. The important shell plate engineering bending models are supported in Workbench DesignModeler by providing for the DesignModeler creation of surface models subsequently analyzed using ANSYS plate element technology. Beam bending is supported by the creation of line models to which beam cross sections are attached. Planar surface models are used to support analysis of Plane Stress, Plane Strain and Axisymmetric problems. Later we will use this same solid to create a three-dimensional surface model.

Where to Find the Files Used in the Tutorials Each of the tutorials uses existing mesh or geometry files.

The Preparation step of each tutorial will indicate the necessary files. You will find the appropriate files on the ANSYS Customer Portal. Typographical Conventions Used In This Manual Several typographical conventions are used in the text of the tutorials to facilitate your learning process. Different type styles are used to indicate graphical user interface menu items and text interface menu items e. The text interface type style is also used when illustrating exactly what appears on the screen or exactly what you need to type in the text field in a dialog box. Instructions for performing each step in a tutorial will appear in standard type. A mini flow chart is used to guide you through the navigation pane, which leads you to a specific task page or dialog box. For example, Mesh Generation Create Size Functions indicates that Size Functions is selected in the Create group box in the Mesh Generation task page. or Models Viscous Edit indicates that Models is selected in the navigation pane, which then opens the corresponding task page.

In many cases, analysts use the finite element method to perform parametric studies on potential designs to size parts, weed out less desirable design scenarios, and predict system behavior under load. In this book, we discuss common pitfalls encountered by many finite element analysts, in particular, students encountering the method for the first time. We present a variety of simple problems in axial, bending, torsion, and shear loading that combine the students' knowledge of theoretical mechanics, numerical methods, and approximations particular to the finite element method itself. We also present case studies in which analyses are coupled with experiments to emphasize validation, illustrate where interpretations of numerical results can be misleading, and what can be done to allay such tendencies. Challenges in presenting the necessary mix of theory and applications in a typical undergraduate course are discussed. We also discuss a list of tips and rules of thumb for applying the method in practice.

Essentials of the Finite Element Method explains the basics of FEM, then relates these basics to a number of practical engineering applications. Specific topics covered include linear spring elements, bar elements, trusses, beams and frames, heat transfer, and structural dynamics. Throughout the text, readers are shown step-by-step detailed analyses for finite element equations development. The text also demonstrates how FEM is programmed, with examples in MATLAB, CALFEM, and ANSYS allowing readers to learn how to develop their own computer code. Provides complete and unified coverage of the fundamentals of finite element analysis Covers stiffness matrices for widely used elements in mechanical and civil engineering practice Offers detailed and integrated solutions of engineering examples and computer algorithms in ANSYS, CALFEM, and MATLAB.
