Predicting Solute Transport in Groundwater Using Simulation
In order for groundwater to be useful for irrigation and drinking, we need to understand how its various solutes move through the water. The Subsurface Flow Module includes features for this.
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 Envelope 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 Simulation
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.
