FEM: Frequently asked questions about the finite element method (FEM)
The finite element method (FEM) is a numerical technique for solving complex physical problems.
The finite element method (FEM) is a numerical technique for solving differential equations that is used in many areas of engineering and physics. The FEM breaks down a complex problem into smaller, easy-to-handle parts called “elements”. These elements are mathematically modeled to approximate the solution of the overall problem.
Here is a basic explanation of how the finite element method works:
Discretization of the domain: First, the physical problem or domain is divided into smaller, non-overlapping elements. These elements can have different shapes, such as triangles or quadrilaterals in 2D or tetrahedrons or hexahedrons in 3D. The boundaries of these elements are called “nodes”.
Setting up the equations: Equations based on the laws of physics (e.g. Navier-Stokes equations in fluid mechanics or the heat conduction equation in heat transfer) are set up for each element. These equations describe the behavior of the element in relation to the desired quantity, such as displacements, temperature or pressure.
Assembling the global systems of equations: The equations for all elements are assembled into a global system of equations that covers the entire domain. This is done by considering the boundary conditions and the interactions between the elements.
Solving the system of equations: The resulting system of equations is usually a system of algebraic equations. This system is solved to calculate the unknown quantities (e.g. displacements or temperature distributions). There are various numerical solution methods, including iterative methods such as the conjugate gradient or direct solution algorithms such as Gaussian elimination.
Post-processing: After the system of equations has been solved, the expected results can be extracted in relation to the quantities sought. This can include the calculation of stresses, deformations, temperature distributions or other physical quantities.
The finite element method is extremely versatile and can be used in a wide range of applications, including structural mechanics, heat transfer, fluid mechanics, electromagnetics and many others. It allows complex geometric shapes and boundary conditions to be taken into account and is therefore a powerful tool for analyzing and solving physical problems in engineering and scientific disciplines.
