How to Create Outstanding Sound Performance in Vehicles
Just because you’re in a car, doesn’t mean the sound quality should be subpar. A guest blogger demonstrates how to use acoustics simulation to optimize sound performance in vehicles.

Modeling Thermal Ablation for Material Removal
When certain materials are heated to a certain point, they go directly from the solid to the gas phase in a process called ablation. Learn how to model the thermal ablation process here.

How to Choose Between Boundary Conditions for Coil Modeling
3 approaches for truncating a domain when modeling an EM coil in free space: the Magnetic Insulation and Perfect Magnetic Conductor boundary conditions as well as the infinite element domain.

Accessing External Material Models for Magnetic Simulations
Get a demonstration of how access external material models for EM simulations with a hysteresis example. Plus, get an overview of the available functionality for modeling ferromagnetic materials.

Modeling Coils in the AC/DC Module
A key concept when it comes to coil modeling is closing the current loop. Learn how to do so when modeling coils using the AC/DC Module and COMSOL Multiphysics®.

Control Current and Voltage Sources with the AC/DC Module
Did you know that you can use the Terminal boundary condition to dynamically switch between excitation types during a transient simulation? This is useful for modeling power supply, for example.
