This document provides an overview of analysis methods and the finite element analysis (FEA) process using ANSYS software. It describes the benefits of analysis and the typical product design cycle. It also summarizes the main analysis methods including analytical, numerical using finite element method (FEM), and experimental testing. The document outlines the basic steps of FEA using FEM including creating the model geometry, meshing, applying loads and boundary conditions, solving, and reviewing results.

6. METHODS OF ANALYSIS
There are three types of Analysis
1. Analytical Method
Classical method 100 % accurate but it will take very long time to solve. SOM (we can’t solve complex problems)
2. Numerical Method
We divide our models in small segments for calculation.
• FEM (finite element method)
• FVM (finite volume method)
• BEM (boundary element method )
• FDML (finite differential method)
3. Experimental Method
100% Accurate result more costly so much time it will take because we create a real object than do analysis on t
that.

7. FEM (FINITE ELEMENT METHOD)
• It will gives us a approx. result solve any type problem (ANSYS/ NX NESTRAN/ HYPERMESH)
FEM : Finite Element Modeling
FEA : Finite Element Analysis
Implementation of FEA via Computer is called FEM Method.

8. 0D Element : to calculate the CG (Center Gravity) . We can apply load on 1 node.
1d Element : 2 nodes
With same cross section on both nodes. (BEAM / LINK/ ROD) with 6 type of freedom MX, MY ,MZ
2D Element : Area
3d Element : we can analysis on 3 nodes, 4 nodes , 8 nodes , solid
ELEMENT TYPES

9. FEA STEPS
1. Creation of Continuum (Continuous) model
2. Discretization (Meshing)
3. Checking for conversations
4. Apply Boundary conditions (Fixing Part, Support, Apply Loads)
5. Solving
6. Review (Post Processing)
Result

10. TYPES OF MATERIALS
1. Isotropic (Property are Same in 3 plane)
2. Orthographic (Changes in every plane)
3. Anisotropic (Crystal Property change in every plane)

13. SKETCHER
1. Open ANSYS workbench
2. Select any Analysis system from tool box & drag it in to project schematic or double click or right click on project
schematic > new analysis system
3. Units change : units menu bar > select units or got to unit system to add more units from templates
4. Double click on geometry or right click on geometry > import to import any cad model (other software file)
5. Select sketch tool and select any plane click sketch tools
6. And select sketch orientation
7. Then draw a closed profile
8. Click generate to finish your sketch
9. Then click modeling tab to return back on modeling tool
10. After that you can apply any solid modeling tool on that sketch you have create in previous steps.

14. EXTRUDE
to create a extrude / Boss Feature in Ansys Modeler you will follow these steps:
1. Select any plane
2. Click sketch tool and click sketch tab to activate all sketch related tools
3. Sketch any closed geometry
4. After completion of your sketch click Generate tool
5. Click Modeling tab
6. Click Extrude command and select you sketch
7. Define necessary parameters for extrude (depth/ condition)
8. Click generate
9. Sketch will convert in to a solid model.
