Analyzing Vibrations in Rotating Machinery Due to Bearing Misalignment

June 25, 2019

You can use structural analysis to compare the angular velocity, axial displacement, and bearing reaction moment on the shaft for rotating machinery with aligned and misaligned bearings.

Automatic Time Step and Order Selection in Time-Dependent Problems

June 20, 2019

Here’s an intro to the time-dependent solver log in COMSOL Multiphysics® and an in-depth look at the theory behind discrete time-stepping schemes and optimal time steps and discretization orders.

Using Simulation Software in the Courtroom

June 17, 2019

Simulation is inherently a representation of reality. In court, lawyers establish what did or did not happen in reality and why. So what happens when simulation software is used in a legal case?

Introduction to Modeling Acoustic-Structure Interactions in COMSOL®

June 12, 2019

To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.
