A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... Mehr lesen
A hinge between two mechanical components is modeled by coupling two rigid connectors. This method can be used for simulating many types of mechanisms. In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of ... 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
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
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. Mehr lesen
This simple example covers the heating of a finite slab and how the temperature varies with time. We will set up the problem in COMSOL Multiphysics after which we compare the solution to the analytical solution. 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
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
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
Uncertainty Quantification (UQ) is used to study the effect of manufacturing variation on the performance of Piezoelectric Energy Harvester. This tutorial shows how UQ studies are specified for a frequency domain study that calculates the energy harvester's power output. Mehr lesen
