This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two-story one-family house consisting of 10 rooms is analyzed. The steady state sound pressure level and energy density distributions are analyzed for a monopole source located in ... En savoir plus
A Luneburg lens is a type of graded index, or GRIN lens, in which the gradient of the refractive index leads to special focusing properties. This example model uses the Geometrical Optics interface to compute the curved ray trajectories in the graded-index medium. En savoir plus
The suite of models examine the air cooling of circuit boards populated with multiple integrated circuits (ICs), which act as heat sources. Two possible cooling scenarios are depicted: vertically aligned boards using natural convection, and horizontal boards with forced convection (fan ... En savoir plus
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... En savoir plus
The Keck Telescope is a 10 meter diameter telescope with a Ritchey-Chretien optical design. It is noted for being one of the first large optical telescopes to utilize a lightweight segmented primary mirror. This tutorial demonstrates how to use built-in polygonal mirrors from the COMSOL ...

In this example a thin curved membrane is built and solved using the Shell interface. This model is a widely used benchmark model denoted the Scordelis-Lo roof. The computed maximum z-deformation is compared with the value given in Proposed Standard Set of Problems to Test Finite ... En savoir plus
This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... En savoir plus
Layered shell elements, which are used for modeling composite shells, often connected to solid and shell elements in cladding or side-by-side configuration to represent a realistic structure. For such applications, it becomes important to connect layered shell element correctly and ... En savoir plus
This tutorial shows how to evaluate the harmonic response of a structure with a moderately nonlinear behavior. A nonlinear problem can only be solved using time-domain analysis. A way to speed up the computation is to use a linearized frequency response analysis to provide good initial ... En savoir plus
