The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. Read More
A line array of eleven spherical hydrophones embedded in a neoprene coating is modeled in 3D. The sensitivity of the array is analyzed with regard to varying angles of incidence of the background pressure field. The array directivity function is computed and compared to the analytical ... Read More
This tutorial demonstrates how to model ultrasound imaging in human tissue using an imaging probe composed of piezoelectric arrays that generate steered and focused beams. Simulating this process requires a transient multiphysics model to accurately capture sound generation, propagation, ... Read More
Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... Read More
This tutorial studies tissue heating induced by high-intensity focused ultrasound (HIFU). The nonlinear propagation of the HIFU signal is modeled using the Nonlinear Pressure Acoustics, Time Explicit physics interface. In this example, the source amplitude is sufficient to generate ... Read More
