## Using COMSOL Multiphysics to Tackle an Acoustics Simulation Problem

My previous blog focused on a challenging fluid dynamics problem, an area in which I have experience. However, since joining the AltaSim team, I have been learning about many other topics in physics and engineering, including acoustics. After some studying and attending our Acoustic Solutions course, I felt ready to tackle an acoustic problem, break […]

## Differences Between Finite Element Analysis (FEA) and Finite Element Method (FEM)

Finite element analysis (FEA) and finite element method (FEM) are two terms that are often used interchangeably, but they have different meanings and applications. FEM is a “mathematical method” for solving problems of engineering and mathematical physics that involve complex geometries, loads, boundary conditions, and material properties. FEA is the “practical application” of FEM to simulate

## Benefits of the Finite Element Method

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

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

## Using COMSOL Multiphysics to Deconstruct a Complex Problem into a Simpler Version

I love a good challenge, and as the newest member of AltaSim’s team, I am fortunate to have excellent mentors here who constantly challenge me to expand my knowledge. I have been teaching myself how to use COMSOL, and one of my most recent challenges from the team was to solve a turbulent flow problem,

## Incompressible Potential Flow with COMSOL Version 6.2

COMSOL continues to make updates to Version 6.2, and in this month’s tips and tricks video, we are going to demonstrate how you can use the new update for Incompressible Potential Flow, which can be used to replace Laplace’s Equation to initialize fluid flow equations.
