Finite Element Analysis – List of FEA Software’s (Open Source and Commercial Software’s)
What is Finite Element Analysis?
Finite Element Analysis (FEA) is a computer simulation technique used in engineering analysis. It uses a numerical technique called the finite element method (FEM). In this, the object or system is represented by a geometrically similar model consisting of multiple, linked, simplified representations of discrete regions — finite elements.
Equations of equilibrium, in conjunction with applicable physical considerations such as compatibility and constitutive relations, are applied to each element, and a system of simultaneous equations is constructed. The system of equations is solved for unknown values using the techniques of linear algebra or nonlinear numerical schemes, as appropriate.
FEA has become a solution to the task of predicting failure due to unknown stresses by showing problem areas in a material and allowing designers to see all of the theoretical stresses within. This method of product design and testing is far superior to the manufacturing costs which would accrue if each sample was actually built and tested.
Types of Finite Element Analysis
There are generally two types of FEA analysis: 2D modeling, and 3D modeling. While 2D modeling conserves simplicity and allows the analysis to be run on a relatively normal computer, it tends to yield less accurate results. 3D modeling, produces more accurate results while it can only be run satisfactorily on a faster computer effectively. Within each of these modeling schemes, the programmer can insert numerous algorithms (functions) which may make the system behave linearly or nonlinearly.
Linear systems are far less complex and generally do not take into account plastic deformation. Nonlinear systems do account for plastic deformation, and many also are capable of testing a material all the way to fracture.
While being an approximate method, the accuracy of the Finite Element Analysis (FEA) method can be improved by refining the mesh in the model using more elements and nodes, though this will retard the process of converging.
Uses of Finite Element Analysis
A common use of Finite Element Analysis (FEA) is for the determination of stresses and displacements in mechanical objects and systems. It is used in new product design, and also in existing product refinement. A company is able to verify whether a proposed design will be able to perform to the client’s specifications prior to manufacturing or construction. Modifying an existing product or structure is utilized to qualify the product or structure for a new service condition.
In case of structural failure, Finite Element Analysis (FEA) may be used to help determine the design modifications to meet the new condition. However, it is also routinely used in the analysis of many other types of problems, including those in heat transfer, fluid dynamics and electromagnetism. FEA is able to handle complex systems that defy closedform analytical solutions.

The site is devoted to AutoFEM Analysis, the FEA software, which is oriented
towards a broad community of engineers. The important feature of the system is its close relationship with the wellknown system of designing, i.e.,‑ AutoCAD. The most popular graphic system AutoCAD 20072010, 2012 is used as a geometric modeling kernel for the preparation of the finite element model in AutoFEM Analysis. There is a free version AutoFEM Lite for educational purposes, which allows to solve various FEA problems without any limitations in quantities of degrees of freedom.
Is not a comment but a question about the FEM code for heat conduction in solids. which one of the source free codes is best fitted to my problem in heat conduction in solids? I am using a laser to heat a metalic surface and need the temperature profile along the surface as well as inside?
Alexander do you feel that FEA software like AutoFEM analysis will be able to compete with software like Ansys in the future?
