An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... Mehr lesen
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... Mehr lesen
A propeller is the propulsion device of a ship. This model studies the open water performance of the KP505 propeller[1]using the frozen rotor method with RANS turbulence model. Thrust and torque coefficient, and open water efficiency of the propeller at different advance coefficients ... Mehr lesen
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... Mehr lesen
Experiments on dry and wet soil samples are performed to understand their behavior under different loading conditions. In this example, the Extended Barcelona Basic (BBMx) soil model is used to simulate the wetting and drying paths in partially saturated soil samples under cyclic ... Mehr lesen
Reflow soldering is an important process in IC packaging. In reflow soldering, the solder materials are melted to create joints between electrical components and the PCBs for structural and electrical connections. This model demonstrates the process of attaching chips to a PCB by reflow ... Mehr lesen
A lossy ferrite circulator at 3GHz is modeled. Geometrical design parameters are varied to match the impedance for minimal reflection of the fundamental TE10 rectangular waveguide mode. Mehr lesen
A goal for many applications is to predict physics in thin structures, such as shells, without modeling the thickness of the structure. This is because large aspect ratios can cause meshing and geometry analysis problems. This model demonstrates how to use the tangential derivative ... Mehr lesen
The S–N curve, also called the Wöhler curve, is one of the most popular methods for fatigue evaluation. The curve relates stress amplitude to the limiting fatigue life and can be obtained directly from a set of standard fatigue test. Many times our applications are subjected to ... Mehr lesen
In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... Mehr lesen
