One of the most frequently asked questions by beginners to engineering simulation is how to learn finite element analysis, and how to use FEA software. This process is not easy, particularly if you want to learn by yourself, not in university. However, with a little motivation and direction, it is achievable.
What are the steps of FEA?
Course content 4
Step 1 – The component. Step 2 – The loads. Step 3 – Boundary conditions. Step 4 – Modelling issues and assumptions. Step 5 – Building and solving the FEA model. Step 6 – Post-processing the FEA model. Step 7 – Post testing and verification.
What is FEA calculation?
The finite element method is a mathematical procedure used to calculate approximate solutions to differential equations. The goal of this procedure is to transform the differential equations into a set of linear equations, which can then be solved by the computer in a routine manner.
What does FEA do?
Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. Finite element analysis shows whether a product will break, wear out, or work the way it was designed. via
How reliable is FEA?
While designers and engineers often feel that accuracy within 5 percent of the real solution is good enough, depending on the product, FEA packages that produce results accuracy within 1 percent of the real solution and make it easier to set up FEA problems, like SOLIDWORKS Simulation, will provide a level of accuracy via
What is FEA in Ansys?
Ansys Mechanical creates an integrated platform that uses finite element analysis (FEA) for structural analysis. Mechanical is a dynamic environment that has a complete range of analysis tools, from preparing geometry for analysis to connecting additional physics for even greater fidelity. via
Who owns Nastran?
It is available on a variety of platforms including 32/64-bit Windows and Linux. This software was acquired by Autodesk in May 2014. via
What is DoF FEA?
Degree of Freedom (DoF) is a “possibility” to move in a defined direction. There are 6 DoF in a 3D space: you can move or rotate along axis x, y or z. Together, those components describe a motion in 3D. DoF in FEA also do other things: they control supports, information about stresses and more! via
What is the difference between FEM and FEA?
FEM: Developed by engineers in the mid-1950s, FEM provides a numerical solution for a complex problem, which allows for some level of error. FEA: The mathematical equations behind FEM are applied to create a simulation, or what's known as a finite element analysis (FEA). via
How is FEA used in industry?
Finite Element Analysis (FEA) is a simulation tool that is used to analyze and test components and systems strengths and behavior under environmental conditions. In aerospace manufacturing, FEA software is used to predict how aerospace parts will react to structural and thermal loads. via
What are the three processes involved in FEA?
The general procedure of finite element analysis can be split largely into 3 stages: preprocessing for preparation of modeling data, processing for assembly and solution of the equations, and postprocessing for visualization of analysis results. via
What are the basic steps of FEM?
What are isoparametric elements?
When a particular coordinate s is substituted into [N] yields the displacement of a point on the bar in terms of the nodal degrees of freedom u1 and u2. Since u and x are defined by the same shape functions at the same nodes, the element is called isoparametric. via

Finite element analysis (FEA) is the process of simulating the behaviour of a part or assembly under given conditions so that it can be assessed using the finite element method (FEM).
Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects. Finite element analysis shows whether a product will break, wear out, or work the way it was designed.
