So, are you ready to discover the power of FEM in COMSOL Multiphysics? Let’s get started!
The Basics of the Finite Element Method
The finite element method (FEM) is a strong numerical technique. It’s used in engineering to tackle complex problems. This method approximates solutions to partial differential equations (PDEs).
It simplifies a function using linear combinations of basis functions. These are created based on the geometry and the specific problem at hand.
The finite element method is great because it breaks down space into smaller parts. This allows for a more precise representation of the problem area. These parts can be evenly or unevenly spread out, depending on the problem.
Theory and Development
The theory behind the finite element method has come a long way since the 1940s. It provides error estimates for numerical solutions. This makes FEM a dependable method used across many engineering fields.
Engineers and professionals use the finite element method to analyze and solve different problems. It’s useful in areas like structural analysis, fluid dynamics, and heat transfer. FEM can simulate and improve real-world situations.
