Student Team Wins R&D Award for Optimizing a Mini Race Car

July 22, 2015

The winning team of the 2014 Formula 1 in schools competition, an international student car building challenge, used COMSOL Multiphysics® to optimize the topology of their car’s wheels.

Fitting Measured Data to Different Hyperelastic Material Models

June 24, 2015

Want to fit your experimental data to different hyperelastic material models? You can with the Optimization interface in COMSOL Multiphysics®, which lets you fit a curve to multiple datasets.

New Book on Topology Optimization for Electromagnetics

July 7, 2014

Whether you’re a student or an industry engineer, read Multiphysics Simulation: Electromechanical System Applications and Optimization, a reference guide on simulation and topology optimization.

Understanding Drug-Eluting Stents at Boston Scientific

June 18, 2014

Stents open plaque-blocked arteries, but when an excessive amount of tissue grows over a bare metal arterial stent, it can cause the artery to narrow again in a process called restenosis.

Optimizing Heater Power for Thermal Processing

February 17, 2014

We demonstrate a useful approach for process control modeling and optimization using COMSOL Multiphysics® and the Optimization Module.

Using Gradient-Free Optimization

August 2, 2013

The COMSOL Optimization Module includes both gradient-based and gradient-free optimization techniques. Whereas the gradient-based optimization method can compute an exact analytic derivative of an objective function and any associated constraint functions, it does require these functions to be smooth and differentiable. In this blog post, we examine the use of the gradient-free optimizer, which can consider objective function and constraints that are not differentiable or smooth. The dimensions of a spinning wheel are optimized to reduce the mass while maintaining […]

Metamaterials Make Physics Seem Like Magic

February 26, 2013

Metamaterials are a new and emerging technology with vast potential to reshape our views on what is and isn’t possible in this physical world of ours. Unlocking the mysteries and overcoming the obstacles associated with metamaterials would lead to a host of technological advances once thought impossible by even the most imaginative of individuals. From making computer chips smaller and faster than the most advanced current ones, to protecting structures from earthquakes, to developing imaging technology that doesn’t harm tissue […]
