Maximizing Eigenfrequencies with Shape and Topology Optimization
Unwanted resonance can have effects of varying severity, whether it be a mild nuisance for an automotive trim or a dangerous failure in civil engineering. One strategy for avoiding unwanted mechanical resonance is to increase the lowest natural frequency of the system in question.
This blog post demonstrates how to maximize the lowest eigenfrequency using shape and topology optimization so that the likelihood of resonance can be reduced.

Modeling Sound Transmission Loss Through a Concrete Wall
Thin walls can allow sound to travel between rooms, disturbing building residents or interrupting business operations in workplaces. When constructing buildings, it's therefore important to predict the sound transmission loss of the building components.

Modeling Periodic Electric Signals and Their Thermal Effects
Signals such as electrical pulse trains can be simulated via time-domain modeling, but it’s also possible to efficiently compute the linear response via a Fourier transform approach. In this blog post, we look at how to model an electrical excitation that is periodic and how this can often be reduced to consider a single period.
