Modeling Speaker Drivers: Which Coupling Feature to Use
Explore how to model 4 different speaker drivers, including moving-coil transducers, balanced armature receivers, piezoelectric drivers, and electrostatic drivers.
Simulating MEMS Accelerometers and Gyroscopes Used in Inertial Measurement Units
Many autonomous vehicles rely on IMUs for navigation. Here, we show how the MEMS Module can help you model the gyroscopes and accelerometers used in IMUs.
Computing and Visualizing Satellite Orbits in COMSOL®
Here, we introduce a new, out-of-this-world tutorial model of a spacecraft in orbit.
Modeling Piezoelectricity Using the Discontinuous Galerkin Method
COMSOL Multiphysics® version 6.0 introduced a feature for modeling piezoelectric devices that is more convenient than alternative methods. Here’s how to use it in your models.
Axisymmetric Solid Mechanics with a Twist
As of version 6.0, you can easily include circumferential displacements in 2D axisymmetric models using the Solid Mechanics interface. Check out one example here.
Validating an Acoustic Ray Tracing Simulation of a Chamber Music Hall
The well-known Konzerthaus Berlin theater boasts 3 separate halls: The Grand Hall, the Small Hall, and the modern Werner Otto Hall. Here, we explore the acoustics of the Small Hall with simulation.
