When combined, these two modes give lower cross-polarization at the antenna aperture. The excited TE mode from a circular waveguide passes along the corrugated inner surface of a circular horn antenna where a TM mode is also generated. In this model, we will couple two physics: electrical currents and heat conduction.Īfter completing this tutorial, you can learn more about each step in the modeling workflow through the COMSOL Learning Center. RF Module New App: Corrugated Circular Horn Antenna Simulator. The temperature in the busbar rises due to resistive heating. The part library includes a variety of cylindrical and spherical lenses, cemented doublets, a beam splitter, paraboloidal reflectors, prisms. A pair of bolts on the other end of the busbar are grounded, thus establishing an electrical potential difference. In order to facilitate fast and efficient geometry set-up for ray optics modeling, the Ray Optics Module includes a part library with predefined geometry components. An electric potential is applied to the single bolt on one end. The busbar is made of copper and contains bolts made out of titanium. To demonstrate the use of the modeling workflow, we simulate the Joule heating of a busbar. You will also learn how to use the Application Builder, which allows you to transform a finite element model into an easy-to-use simulation application. The Power and Benefits of Simulation are Accessible to Everyone. Before clicking Run, make sure again that you have closed all COMSOL sessions.In other browsers, such as Chrome, you have to select the downloaded file and run it, see step 3 below. To help the learning process, there is a streamlined workflow you can follow that is reflected throughout the user interface of the software.įollow along with this tutorial as we guide you through the entire model building process and provide you with a detailed overview of the modeling workflow, which consists of the following steps: In some browsers, such as Internet Explorer, you get a dialog box where you can click Run directly after download. This may be suitable with 64 bit Windows ?.A proper introduction on how to set up and run a model in COMSOL Multiphysics ® is essential when learning how to use the software. That is full offline installer and standalone setup for COMSOL Multiphysics. ? Click on on beneath button to begin COMSOL Multiphysics Free Download. System Requirements For COMSOL Multiphysics
