Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... Mehr lesen
The homogenized material properties of a composite are computed based on the temperature-dependent properties of matrix and fiber. The homogenized parameters are compared to the analytical values derived from the rule of mixtures. This is an extension of model https://www.comsol.com ... Mehr lesen
This demonstration app will fit a surface through a set of points using radial basis functions and will write out a COMSOL-format file of a smooth NURBS surface that passes through all of the points. The function describing the surface can also be written to a text file. The point data ... Mehr lesen
This example demonstrates a simulation setup for exciting surface plasmon polaritons using Otto and Kretschmann configurations. The underlying mechanism is enabled by the interplay between total internal reflection and evanescent-wave coupling phenomena. It also calculates the ... Mehr lesen
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Mehr lesen
A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... Mehr lesen
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Mehr lesen
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ... Mehr lesen
In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... Mehr lesen
This example demonstrates how to compute transmission line parameters such as series resistance, series inductance, shunt conductance, and shunt capacitance per unit length using the predefined Transmission Line RLGC Parameters multiphysics interface. The demonstration also includes the ... Mehr lesen
