This paper investigates the effects of electrical loading due to metallic interdigital transducer (IDT) on surface acoustic wave (SAW) velocity in SAW resonators by simulation using FEM in COMSOL Multiphysics. The IDT electrodes fabricated over the piezo-substrate short circuit the parallel electric ...

Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). In COMSOL Multiphysics software, the AC/DC module is selected and the In-plane electric currents...
Altair Simulation 2022 has been launched with much of the focus on next-generation connectivity, as well as circuit board and electronics design capabilities; as well as a myriad of updates to Altair’s traditional solutions. Altair Simulation 2022 includes more capabilities for circuit board and el...
(or MHD) effect. The model adopted here was derived from the Navier-Stokes equations for Newtonian incompressible fluid using the k-ε turbulence model and coupled with the Maxwell equations. The equations were solved using COMSOL Multiphysics®. The 3D numerical simulations allowed obtaini...
The behaviour of the signal charge carriers in CdTe should be well understood because it has an impact on the performance of the readout channels. For this purpose the Finite Element Method (FEM) Multiphysics COMSOL software package has been used to simulate the behaviour of signal charge ...
The COMSOL can automatically adjust the density of the mesh according to the intensity distribution of light, so as to achieve the variations in field intensity in more detail. Because the FEM requires triangulation of the proposed PCF-PBS geometry for numerical analysis, comprising the vertex ...
For the simulation, the main finite element package, COMSOL Multiphysics v5.3a, and two add-on modules, Electric Current (EC) and LiveLink for MATLAB, must be installed on a computer. This example simulation takes ~ 15 min to run on a Dell Precision T5810 workstation with an E5-...
I wouldn't think that simply changing the simulation time settings should have this effect on the model. Now I just started using COMSOL last month, so I'm pretty new to this. However, one of my colleagues who is a little more familiar with the software says it doesn't make sense to...
