Benefits of the Finite Element Method

General, Multiphysics Modeling, Simulation, Thought Leadership /

Computational simulation is a powerful tool for solving complex engineering problems that involve the finite element method (FEM). FEM is a numerical technique that divides a domain into smaller elements and approximates the governing equations at each element. By using computational simulation, engineers can perform FEM analysis faster, more accurately, and more efficiently than using

Finite Element Analysis and the Benefits of Computational Simulation

General, Multiphysics Modeling, Simulation, Thought Leadership /

Finite element analysis (FEA) is a method of solving complex engineering problems involving structures, fluids, heat transfer, and other physical phenomena. FEA divides the problem domain into smaller and simpler parts called finite elements, and then applies mathematical equations to describe the behavior of each element and the interactions among them. FEA can find approximate

Exploring Sound Absorption Through Acoustic Metamaterials

Acoustics, COMSOL Multiphysics, Thought Leadership /

The fast-growing area of acoustic metamaterials, specifically those composed of subwavelength periodic artificial structures with specific designs, has drawn significant research attention. In this article, we compare acoustic metamaterials to the limitations of conventional acoustic materials in sound absorption, and what we discover is acoustic metamaterials are far more effective for low-frequency applications. LIMITATIONS OF
