Superfilling Electrodeposition
This example illustrates the concept of superfilling in electrodeposition. The deposition rate is accelerated in concave areas of the surface, where the concentration of a surface catalyst is increased due to the area contraction of the moving boundary. En Savoir Plus
Forces and Moments on Bevel Gears
This tutorial model simulates a pair of straight conical bevel gears. The gears are modeled as rigid, but one of the gears is fixed while the other is hinged on a rigid bar. The rigid bar is also hinged at a point lying on the axis of the fixed gear. A transient analysis is performed to ... En Savoir Plus
Solid Multilayer Shell Comparison
This example demonstrates a benchmark test showing that _Electric Currents in Layered Shells_ physics interface can be used to obtain the same results as when the model is solved with the _Electric Currents_ interface based on a solid 3D structure. En Savoir Plus
Damping Pad with a Constrained Layer
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... En Savoir Plus
Primary Creep Under Nonconstant Load
In this model example, you will study the creep behavior of material under non-constant loading. You will model the primary creep using a Norton-Bailey law and study the difference between the time hardening and the strain hardening methods available in COMSOL Multiphysics. The model is ...

Designing a Waveguide Diplexer for the 5G Mobile Network
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... En Savoir Plus
Heat Transfer Modeling in Cellulosic Material Oxidation
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... En Savoir Plus
Interpolating Material Data on a Regular Shape as an Alternative to Building an Irregular Geometry
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... En Savoir Plus
Chlorine Discharge Global Model
Plasma discharges containing chlorine are commonly used to etch semiconductors and metals in microelectronics fabrication. This tutorial model studies chlorine plasma discharges using a global (volume-averaged) diffusion model. Global diffusion models can run simulations in a fraction ... En Savoir Plus
Modifying Imported CAD Geometry with the Deformed Geometry Interface
When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ...
