How to Model Roller Bearings in COMSOL Multiphysics®
Roller bearings are one of the most commonly used industrial components, found in gearboxes, conveyors, motors, and rolling mills, among other devices. Learn how to model this part in COMSOL®.

Analyzing the Deformation of a Biomedical Stent with Simulation
By studying deformation in an arterial stent, biomedical engineers can account for unwanted effects like dogboning and foreshortening long before the device is ever implanted.

Optimizing Thermophotovoltaic Designs with Heat Transfer Simulation
Thermophotovoltaic (TPV) systems, known for their flexible fuel choice options, immovable parts, and potential for efficient power generation, can be optimized with heat transfer modeling.

Analyzing the Viscous and Thermal Damping of a MEMS Micromirror
Micromirrors are efficient and inexpensive. Here, we go over 2 types of analyses for a MEMS micromirror design, frequency-domain and transient, using the COMSOL® software.

Applying and Interpreting Saint-Venant’s Principle
Saint-Venant’s principle is found in most structural engineering textbooks, but what is its exact meaning? We go over its history, definition, and relevance to mechanical analyses.

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.

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.

How to Model Fluid-Structure Interaction in a Water Balloon
They’re not just for playing games in the backyard: Water balloons are also an example of fluid–structure interaction in a nonlinear elastic material. Learn how to model this effect…
