Using the Discontinuous Galerkin Method to Model Linear Ultrasound

January 26, 2017

You can easily model acoustically large problems, like linear ultrasound, with a predefined physics interface that uses a memory-efficient approach called the discontinuous Galerkin method.

Report from the Joint CAA-ASA Acoustics Conference

July 8, 2013

Last month, the Acoustical Society of America (ASA) and the Canadian Acoustical Association (CAA) held the 21st joint meeting of the International Congress on Acoustics (ICA) in Montreal, Canada. This joint congress is one of the major acoustics conferences of 2013, featuring a range of parallel sessions that covered most topics in acoustics. These included, among other things, psycho acoustics, underwater acoustics, transducer modeling, acoustics of musical instruments, nonlinear acoustics, and many more. This year’s acoustics conference also featured a […]

Modeling Acoustic Damping Processes

May 23, 2013

Mufflers are often located in exhaust systems or on heat, ventilation, and air conditioning (HVAC) systems, where their key functionality is to dampen the noise that is emitted from the system. A correct description of the acoustic damping (absorption and attenuation) processes in the muffler is important when designing and modeling these systems.
