Using Simulation to Analyze Arterial Wall Mechanics

October 12, 2015

Studying arteries from a mechanical standpoint requires a reliable model that can fully describe the anisotropic nonlinear response of this biological soft tissue.

Modeling Microresonators with Electrostatic Actuation

October 8, 2015

Learn how to model electrostatically actuated MEMS resonators and get an intro to terms such as equilibrium point, pull-in, pull-in voltage, and time harmonic response of a biased resonator.

Optimizing the Power of a Piezoelectric Energy Harvester

October 2, 2015

When it comes to a piezoelectric energy harvester, the design configuration should maximize the level of power transfer. How can simulation be used to improve the design of an energy harvester?

A Thermoviscous Analysis of Acoustic Radiation Forces

Improving Nuclear Reactor Designs with Simulation

September 24, 2015

Take a look inside the dynamics of a nuclear reactor — and then see how you can use multiphysics simulation to improve their design.

Finding a Structure’s Best Design with Topology Optimization

September 23, 2015

Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.
