Examining Heat Transfer in a Friction Stir Welding Process
Friction stir welding (FSW) is an efficient, cost effective, and environmentally friendly process that can be optimized by studying the heat transfer involved via modeling.

Analyzing a Loudspeaker Array with a Bessel Panel Benchmark Model
Engineers can design optimized loudspeaker arrays and other acoustics systems by analyzing a benchmark model of a Bessel panel system like the one featured in this blog post.

Predicting the Stability of Rotor Systems with the COMSOL® Software
Instability in a rotor system can lead to catastrophic failure. Fortunately, engineers can predict the stability of rotor systems by performing stability analyses with the Rotordynamics Module.

Evaluating a Turbocharger Design with Rotordynamics Analysis
Like a “turbocharged” cup of coffee, an actual turbocharger also increases speed, but in the operation of a combustion engine, not how fast your morning cup wakes you up.

Optimizing Thermal Processes in Carbon Manufacturing with Simulation
A guest blogger from SGL Carbon GmbH demonstrates how his organization uses heat transfer simulation to optimize thermal processes in carbon manufacturing.

How to Provide Structural Stability in Thermal Expansion Simulations
Say you want to compute thermal expansion and stresses in an object, but you don’t know what constraints you need. That’s where the Rigid Motion Suppression feature comes in.

How to Perform a Nonlinear Distortion Analysis of a Loudspeaker Driver
For a thorough and complete analysis of a loudspeaker driver design, acoustics engineers need to perform nonlinear time-domain studies in addition to frequency-domain studies.

What Is the Doppler Effect?
A siren passes by and you hear a change in pitch. A bug swims across a puddle, causing ripples on the surface. A star in the sky has a reddish hue. These are all examples of the Doppler effect.
