Tutorials in this series deal with creating and manipulation of boundary layer meshes. In these tutorials you will learn how to set up a boundary layer mesh and modify the settings for an automatically created boundary layer mesh. For physics-controlled meshing a boundary layer mesh is ... Mehr lesen
The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ... Mehr lesen
This model analyzes the operation of a micromirror in air and the effects of thermoviscous damping on the vibration response. The model includes thermal losses in the structure as well as thermoviscous acoustic phenomena. The model couples the Thermoelasticity multiphysics interface to ... Mehr lesen
This model studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. Mehr lesen
In a gearbox, vibrations due to gear rattling and bearing misalignment are well known sources of noise. In this example, two shafts connected through a pair of gears are considered. The shafts are supported on roller bearings at their ends. Initially, the driven shaft is unloaded and the ... Mehr lesen
This example applies an Oldroyd-B fluid to model the thinning of a viscoelastic filament under the action of surface tension. For times smaller than the polymer relaxation time, the filament develops a beads-on-string structure. At times much larger than the relaxation time, the solution ... Mehr lesen
An axisymmetric model of a rigid piston in an infinite baffle is used to exemplify the Exterior Field Calculation feature of the Acoustics Module. The radiation results provided by the COMSOL Multiphysics® software are compared to analytical results for the on-axis radiation ... Mehr lesen
A modern high-power industrial fiber laser system can deliver up to 3kW of single-mode laser radiation on to surfaces to be cut, drilled, welded or marked. Even using highly transmissive materials, the optical component used to focus the laser beam onto target surfaces can be affected ... Mehr lesen
Lithium-ion batteries can have multiple active materials in both the positive and negative electrodes. For example, the positive electrode can have a mix of active materials. These materials can have different design properties (volume fraction, particle size), thermodynamic properties ... Mehr lesen
Dieses Modell beschreibt das Verhalten einer Lithium-Ionen-Akku-Einheitszelle, die anhand einer idealisierten dreidimensionalen Geometrie modelliert wird. Die Geometrie ahmt die strukturellen Details in den porösen Elektroden nach. Solche Modelle werden als heterogene Modelle ... Mehr lesen
