Dieses Modellbeispiel zeigt, wie Sie die nichtlineare Ausbreitung einer zylindrischen Welle mithilfe dem im Acoustics Module von COMSOL Multiphysics verfügbaren Physik-Interface Nonlinear Pressure Acoustics, Time Explicit modellieren. Das Interface implementiert das System der ... Mehr lesen
This example involves a static 2D axisymmetric analysis of a piezoelectric actuator using the Piezoelectric Devices physics interface. It models a radially polarized piezoelectric tube, as described by S. Peelamedu and co-authors. An application area where radially polarized tubes are ... Mehr lesen
This model simulates a GaN based light emitting diode. The emission intensity, spectrum, and quantum efficiency are calculated as a function of the driving current. Direct radiative recombination across the band gap is modeled, as well as non-radiative Auger and trap-assisted ... Mehr lesen
In this verification example, forced random vibrations of a simply-supported deep beam are studied. The beam is loaded by a distributed force with a uniform power spectral density (PSD). The output PSD is computed for the displacement and bending stress response. The computed values are ... Mehr lesen
This is an example of a Fabry-Perot cavity, the simplest optical resonator structure. It is a classical problem in optics and photonics. Two methods are shown for computing the Q-factor. The losses in this model are purely via radiation away from the resonator. Mehr lesen
A detailed description of these models can be found in our blog post “How Should I Evaluate Singular Stress Fields?”. The models are: notchedStrip.mph – Model for the initial studies of the stress field properties. singularityPower.mph – Small model solving the transcendental equation ... Mehr lesen
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... Mehr lesen
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

These two models show how to set up a magnetohydrodynamics model using either a fully coupled approach, or a one-way coupled approach. A more detailed description of these models can be seen in the blog post "Building a Magnetohydrodynamic Multiphysics Model in COMSOL®". Mehr lesen
This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results. Mehr lesen
