Finite element meshing
Did you know?
Mesh generation is the practice of creating a mesh, a subdivision of a continuous geometric space into discrete geometric and topological cells. Often these cells form a simplicial complex. Usually the cells partition the geometric input domain. Mesh cells are used as discrete local approximations of the larger domain. Meshes are created by computer algorithms, often with human guida… WebFeb 5, 2024 · This approach is called finite element modeling (FEM). Analyzing a model created with FEM is called finite element analysis, or FEA. (The two terms, FEM and FEA, are often used interchangeably.) This article introduces the concepts of FEM and how it’s used to solve a wide variety of real-world problems.
