2 Outline Introduction to Finite Element Analysis Introduction to ANSYS 3/30/2015
3 The finite element method (FEM) is a numerical technique for solving a mathematical model of a physical problem. The FEM is a computer aided numerical technique for obtaining approximate numerical solutions to a set of equations of calculus that predict the response of physical systems subjected to external influences (like forces, pressure, temperature, voltage, etc). The FEM deals with the physical model instead of the lumped parameters mathematical model, see the second order system example below.
4 Second order system: mass-spring-damper system m x bx Kx F(t) m, b, and K are the lumped parameters of the system.
5 MATLAB Modeling: F FEA Modeling: Force F F Red is minimum deflection Blue is maximum deflection
6 How FEA works: 1. A complex entity is broken up into continuous simple geometric shapes called Elements. 2. Elements are simple geometric shapes like line, triangles, rectangular, pyramids, cubs. 3. Each element has its own shape function which describe the relations among its vertices (Nodes). 4. Each Element in interconnected with its neighbor in all directions by means of Nodes. 5. Any load applied to this single element is distributed to its neighbor correspondingly based on its geometrical features (shape function). 6. The material properties of the complex entity or object are applied to the whole of these elements.
7 FEA solution procedure: 1. Divide the structure into pieces (elements with nodes). 2. Describe the behavior of the physical quantities on each element. 3. Connect (assemble) the elements at the nodes to form an approximate system of equations for the whole structure. 4. Solve the system of equations involving unknown quantities at the nodes (e.g. displacement). 5. Calculate desired quantities (e.g. stress, strain) at selected elements.
8 Discretization and element types: Modeling and solution with FEA is not easy task hence it is based on solving huge number of equations. As a result, FEA software packages are used for calculations and visualization of the results. In next section we are going to introduce ANSYS as a FEA package.
9 ANSYS: ANSYS is a general-purpose software package based on the finite element analysis (FEA). ANSYS program has many finite element analysis capabilities, ranging from a simple, linear, static analysis to a complex, nonlinear, transient dynamic analysis. ANSYS program has a very interesting feature that is can couple different physics to find the solution, e.g. electrostatic/structural, thermal/structural, etc.
10 Typical ANSYS analysis has three distinct phases: Preprocessing phase: Create the Solid model and the Finite element model (meshed model), Define Material properties, Real constants, and Element type. Solution phase: Defining the analysis type, static, transient, modal, harmonic, etc Loads and constraints are applied to either solid model or finite element model, Solving the simultaneous set of equations that the finite element method generates. Postprocessing phase: Reviewing the results of an analysis. It is an important step in the analysis, because we are trying to understand how the applied loads affect the design, how good the finite element mesh is, and so on.
11 Launching ANSYS: Start > All Programs > ANSYS 12.0 > Mechanical APDL (ANSYS) You can run the ANSYS program in two modes: interactive mode (the default), You exchange information with the computer continuously. You can execute a command by selecting its menu path in the GUI or by typing it in directly. The ANSYS program processes the command in real time. Interactive mode allows you to use the GUI, online help, and various tools to create the engineering model in the graphics window and modify it as you work through the analysis. batch mode, You submit a file of commands to the ANSYS program. This command file may have been generated by a previous ANSYS session, by another program, or by creating a command file with an editor.
12
13 (1) Utility Menu: contains functions that are available throughout the ANSYS session, such as file controls, selections, graphic controls, and parameters. (2) Input Line: shows program prompt messages and allows to type in commands directly. (3) Toolbar: contains push buttons that execute commonly used ANSYS commands. More push buttons can be made available if desired. (4) Main Menu: contains the primary ANSYS functions, organized by preprocessor, solution, general postprocessor, and design optimizer. It is from this menu that the vast majority of modeling commands are issued. (5) Graphics Windows: where graphics are shown and graphical picking can be made. It is here where the model in its various stages of construction and the ensuing results from the analysis can be viewed. The Output Window, displays text output from the program, such as listing of data, etc. It is usually positioned behind the Graphics Window and can be put to the front if necessary. Closing output window terminates ANSYS program without saving current data settings.
14 Database and Files: The database stores both your input data and ANSYS results data: - Input data: information to enter, such as dimensions, material properties, and load data. - Results data: quantities that ANSYS calculates, such as displacements, stresses and temperature. Defining the Jobname: Utility Menu > File> Change Jobname The jobname becomes the first part of the name of all files the analysis creates. (The extension or suffix for these files' names is a file identifier such as.db) By using a jobname for each analysis, you ensure that no files are overwritten. Typical files in Ansys: jobname.db,.dbb: Database file, binary. This file stores the geometry, boundary conditions, and any solutions. jobname.log: Log file, ASCII. Contains a log of every command issued during the session. jobname.err: Error file, ASCII. Contains all errors and warnings encountered during the session. jobname.rst,.rth,.rmg,.rfl: Results files, binary. Contains results data calculated by ANSYS during solution. Compatible across all supported platforms.
15 Defining an Analysis Title: Utility Menu> File> Change Title This will define a title for the analysis. ANSYS includes the title on all graphics displays and on the solution output Saving jobs: Utility Menu> File>Save as Jobname.db
16 Restoring jobs: Utility Menu> File> Resume from Exiting the program: Utility Menu> File> Exit
17 UNITS ANSYS does not assume a system of units for intended analysis. Except in magnetic field analyses, any system of units can be used so long as it is ensured that units are consistent for all input data. Units cannot be set directly from the GUI. In order to set units as the international system of units (SI) from Main Menu> Preprocessor Material Props Material Library Units
18 SYSTEM OF UNITS For micro-electromechanical systems (MEMS), it is best to set up problems in more convenient units since components may only be a few microns in size. For convenience, the following tables list the conversion factors from standard MKS units to µmks
19 Defining element types Main Menu> Preprocessor Element Type Add/Edit/Delete.
20 Defining element Attributes In case the model contains many element types and material properties, we need to link each element type with its own material number (or material property) Main Menu> Preprocessor Preprocessor Modeling Create Elements Element Attributes
21 Defining Material Properties We can define any number of material models, each material model is assigned to a certain number. Main Menu> Preprocessor Material Props Material Models
22 Creating Solid Model (Solid Modeling): 1. It is the process of creating solid models in ANSYS environment. 2. A solid model is defined by volumes, areas, lines, and keypoints. 3. Volumes are bounded by areas, areas by lines, and lines by keypoints. 4. Hierarchy of entities from low to high as keypoints < lines < areas < volumes 1. You cannot delete an entity if a higher-order entity is attached to it.
23 Methods of Solid Modeling: There are two approaches to build the model: 1. Top-down modeling: starts with a definition of volumes (or areas), which are then combined in some fashion to create the final shape. 2. Bottom-up modeling: Starts with keypoints, from which you build up lines, areas, etc.
24 Methods of Solid Modeling: 3. Primitives: The volumes or areas that you initially define are called primitives, which are basic entities for the top-down method. 4. Work Plane: Working coordinates can move to any point in the working area to facilitate positioning the primitives. By default the WP coincides with the global origin.

25 Methods of Solid Modeling: 5. Boolean Operations: It is the process of combinations of geometric entities Main Menu > Preprocessor > Modeling > Operate > Booleans
26 Methods of Solid Modeling: 5. Boolean Operations: Common boundary
27 Meshing the solid model (Finite Element Model): Main Menu > Preprocessor > Meshing > MeshTool Meshing Methods: There are two main meshing methods: free and mapped. Free Mesh a. Has no element shape restrictions. b. The mesh does not follow any pattern. c. Suitable for complex shaped areas and volumes. d. Volume meshes consist of high order tetrahedral (10 nodes). Mapped Mesh a. Restricts element shapes to quadrilaterals (areas) and hexahedra (volume) b. Typically has a regular pattern with obvious rows of elements. c. Suitable only for regular shapes such as rectangles and bricks.
28 Meshing the solid model (Finite Element Model): Main Menu > Preprocessor > Meshing > MeshTool Mesh density control Smart Sizing: By turning on Smart Sizing, and set the desired size level. Size level ranges from 1 (fine) to 10 (coarse), defaults to 6. Then mesh all volumes (or all areas) at once, rather than one-by-one. Global Element Sizing: Allows you to specify a maximum element edge length for the entire model (or number of divisions per line): MainMenu>Preprocessor>Meshing>SizeCntrls>ManualSize>Glo bal >Size Different entities can be meshed with different element size by using mesh attribute. Main Menu>Preprocessor>Meshing>Mesh Attributes
29 Analysis type: Main Menu > Solution > Analysis Type>
30 Applying loads and constrains: Main Menu > Solution > Define Load> Apply> Structural> Displacement> On Lines
31 Solve: Main Menu > Solution> Solve> Current LS
32 Main Menu > General Postproc> (POST1) Provides the results for only one time step (substep) Main Menu > TimeHist Postpro> (POST26) Provides the results at specific points in the model over all time steps. Postprocessing: 1. Lists or Plots nodal displacements and shows the deformation. 2. Lists Element forces and moments. 3. Lists or Plots Displacement, Stress, or Strain contour diagrams. 4. POST26 is used for transient, harmonic, and modal analyses. 5. POST1 can be used only to review the results of a steady state analysis or the results of only one substep of other analyses.
33 Calculate the spring stiffness (K) and the maximum stress in the MEMS-based cantilever shown below. Verify your calculations using ANSYS. 6 m F 18 m h L
34 area 1 area 2 Preprocessor: 1. Create area 1 and area 2 in the global coordinate system. 2. Glue (or add) area 1 and area Define the element type to be PLANE In the options of the element, select Plane strs w/thk 5. Define the real constant for PLANE 82 (thickness of the beam, 2 µm). 6. Define the material properties. 7. Mesh the whole structure. (refine the mesh) Solution: 1. Apply loads and solve current load step (LS).
35 area 1 area 2 POST1: 1. List displacement in x-direction of all nodes. 2. Plot displacement contour. 3. Plot deformation of the beam. (Animate as well) 4. Plot the stress contour on the plate.
