Model Deforming Objects with the Arbitrary Lagrangian-Eulerian Method
The combined efforts of Leonhard Euler and Joseph-Louis Lagrange inspired the arbitrary Lagrangian-Eulerian (ALE) method, which we can use to model deforming objects.
Studying the Safety of Tattoos with Mass Spectrometry and X-Rays
When you get a tattoo, what happens to the ink once it enters your skin? In an attempt to answer these questions, researchers turned to mass spectrometry and X-ray fluorescence.
Analyzing the Mechanical Behavior of Cells for Biological Applications
Finite element modeling can be used to analyze the mechanical behavior of biological cells. Guest blogger Björn Fallqvist of Lightness by Design sheds light on this bioengineering topic.
Analyzing White Pupil Échelle Spectrographs via Ray Tracing Simulation
Astronomers use échelle spectrographs to detect far-away planets. To design a white pupil échelle spectrograph with optimized sensitivity, engineers can turn to ray tracing software.
How to Use the Beam Envelopes Method for Wave Optics Simulations
In order to simulate optically large optical systems, you need to solve for Maxwell’s equations, which requires a fine mesh and a lot of computational energy. Enter the beam envelope method.
Evaluating the Performance of a Steam Reformer with COMSOL®
To design a steam reformer for hydrogen production, you need to couple mass, energy, and flow equations. The Chemical Reaction Engineering Module can account for this true multiphysics problem.
Modeling a Sphere Falling on a Water Surface
Get the theory behind a quintessential CFD problem, the oscillating motion of a buoyant sphere, as well as step-by-step instructions for modeling it in COMSOL Multiphysics®.
A Simulation Color Table for Engineers with Color Vision Deficiency
Simulation results often use color to present data and emphasize certain takeaways, but what about engineers with color vision deficiency? Cividis is a color table designed specially for this.
