Predicting the Unpredictable: Simulating Earthquake Mechanics

July 5, 2019

In case of an earthquake, people regularly practice hiding under their desks. Another way to prepare? Using response spectrum analysis to determine the structural stability of a building subject to this type of seismic event.

What Do Lobster Shells Have to Do with Body Armor?

July 3, 2019

Believe it or not, lobster are potentially paving the way for innovations in body armor and soft robotics due to the unique properties of the translucent membrane on the underside of their tails.

Happy Birthday, Maria Goeppert Mayer

June 28, 2019

2, 8, 20, 28, 50, 82, and 126 were the “magic numbers” that led Maria Goeppert Mayer to develop the first mathematical model for nuclear shells in an atom.

How to Automate Meshing in Frequency Bands for Acoustic Simulations

June 26, 2019

There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.

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.

Building a Magnetohydrodynamic Multiphysics Model in COMSOL®

June 19, 2019

Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.

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?
