Computing Capacitance

A capacitor, in its simplest form, is a two terminal electrical device that stores electric energy when a voltage difference is applied across the terminals. The stored electric energy is proportional to the applied voltage squared and is quantified by the capacitance of the device. This ... Читать дальше

Large Deformation Analysis of a Beam

This example studies the deflection of a cantilever beam undergoing very large deflections. The beam is modeled using both the Solid Mechanics interface and the Beam interface. The results are compared with each other and with a benchmark solution from NAFEMS. In addition, a linear ... Читать дальше

Heat Sink

This model is intended as a first introduction to simulations of fluid flow and conjugate heat transfer. It shows you how to: Draw an air box around a device in order to model convective cooling in this box, set a total heat flux on a boundary using automatic area computation, and ... Читать дальше

Evaporative Cooling of Water

This tutorial shows how to couple three physics interfaces to model evaporative cooling. The effects that need to be taken into account are heat transfer, transport of water vapor, and fluid flow. The Wet Surface feature is used to implement the source term for the water vapor and to ... Читать дальше

Inkjet Nozzle — Level Set Method

Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... Читать дальше

Transport and Adsorption

This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions ... Читать дальше

Cable Tutorial Series

In this set of six tutorial models and associated documentation, you can investigate the capacitive, inductive, and thermal properties of a standard three-core lead-sheathed cross-linked polyethylene, high-voltage alternating current (XLPE HVAC) submarine cable (500 mm2, 220 kV). The ... Читать дальше

Modeling of a 3D Inductor

Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic core to increase the inductance, while keeping its ... Читать дальше

Free Convection in a Water Glass

This model treats the free convection and heat transfer of a glass of cold water heated to room temperature. Initially, the glass and the water are at 5 °C and are then put on a table in a room at 25 °C. The nonisothermal flow is coupled to heat transfer using the Heat Transfer module. Читать дальше

Bracket — Transient Analysis

The bracket models are used as an introduction to structural mechanics modeling with the Structural Mechanics Module. The following features are introduced: * The fundamentals: static linear analysis * Parametric study * Including initial strain * Modeling thermal expansion * Adding a ... Читать дальше
