Finite Element Frequency-Domain Analysis in 2DIn this part of the course, we will learn how to set up a model for a frequency-domain analysis in the 2D axisymmetric space dimension using the Model Wizard in COMSOL Multiphysics®. The rotationally symmetric driver is placed in an infinite ...
Zhangxian Deng Send Private MessageFlag post as spam Hi, I am trying to simulate a 3-D beam in COMSOL v4.3. This beam is free in one end, and in the other end, I want to applied a sinusoidal boundary displacement input D(t)= Damp*sin(2*pi*f*t). In the Frequency Domain study,...
The basic results of the two methods are validated by present COMSOL simulations and available numerical and experimental data in the literature. An effective reduction of temperature fluctuation is achieved to the scale of 0.1 K, even under two thermal disturbances from different directions: a ...
Commercially available COMSOL Multiphysics suite 4.4 (COMSOL Inc.) was employed for this purpose. A frequency domain analysis was performed using the physics of piezoelectric devices, where a scan over a spectral range of 19 kHz to 25 kHz was executed. Scientific Reports | 6:38041 | DOI:...
To that end, a new variational formulation for the electromagnetic field was developed for 2D axisymmetric geometries with azimuthal magnetic fields (ι-form [17]) and installed into a commercial FEM tool (COMSOL, v6.0)—later validated using complete vector 3D H-form software. FEM computations ...
In this follow-up to a previousblog post on damping in structural dynamics, we take a detailed look at the harmonic response of damped mechanical systems. We also demonstrate different ways of setting up a frequency-response analysis in the COMSOL Multiphysics® software as well as how to int...
The results of numerical calculation show: (1) in the frequency domain, the numerical solution obtained by the finite element method is highly consistent with the analytical solution obtained by the variation-of-parameters method; (2) in the time domain, the numerical solution obtained by the ...
The resultant mode field distribution about the SCPCF core simulated using COMSOL Multiphysics is shown in Fig. 2a. Thus, from the calculated mode field area at the SCPCF core, it is concluded that the HE11 core mode and the quasi-HE22 cladding-like modes are excited23 (inset Fig. 2a)...
one fixed direction of propagation that has normal incidence on the FSS. The analysis includes the reflection and transmission spectra, the electric field norm on the top surface of the unit cell, and the dB-scaled electric field norm shown on a vertical cut plane in the unit cell domain. ...
