These two models show how to set up a magnetohydrodynamics model using either a fully coupled approach, or a one-way coupled approach. A more detailed description of these models can be seen in the blog post "Building a Magnetohydrodynamic Multiphysics Model in COMSOL®". 詳細を見る
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and pull-in ... 詳細を見る
This example investigates the electrical and thermal characteristics of a welding argon arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The electric arc is considered a conductive fluid medium and is modeled using a ... 詳細を見る
The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to ... 詳細を見る
This tutorial demonstrates how to compute the periodic steady-state solution of a nonlinear model problem using an optimization solver. The solver modifies the initial conditions at the beginning of a period to match the solution at the end of the period. The model solves much faster ... 詳細を見る
One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... 詳細を見る
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ... 詳細を見る
This is a transient model of an electromagnetic plunger with stopper restricting the linear motion. The model consists of a magnetic core, nonmagnetic guider, multi-turn coil, nonmagnetic stopper/blocker, and magnetic plunger attached to the spring and damper at the base. The ... 詳細を見る
Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps: The ... 詳細を見る
The model analyses the mode propagation within a nano slot waveguide. In a slot waveguide configuration, two high refractive index slabs (~3.48) are placed adjacent to the low refractive index slot (~1.44). Mode analysis was performed on a 2D cross section of a slot waveguide for an ... 詳細を見る
