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 will show the diplexer characteristics in the Ka-band.

Corrosion Protection of Multiple Oil Platforms

This example extends the corrosion protection system analysis of the single oil platform example by modeling the influence of multiple oil platforms placed in an array. The use of the Current Distribution on Edges, BEM interface significantly reduces the problem size and computational time by modeling all electrodes as cylinders along the edges of a wireframe geometry.

Material Characteristics of Laminated Composite Shell

This model serves the purpose of validation and verification of the Layered Linear Elastic Material model in the Shell interface. In COMSOL Multiphysics, composites are analyzed either based on Layerwise 3D elasticity theory through the Layered Shell interface or based on FSDT-ESL theory through the Shell interface. The First Order Shear Deformation Theory (FSDT-ESL) is implemented in the ...

Electrical Heating in a Busbar

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.

Vdara® Caustic Surface

When the Vdara hotel first opened in Las Vegas, visitors relaxing by the pool would experience intense periods of heat at certain times of the day, at certain times of the year. This intense heat was caused by the reflection of solar radiation from the curved, reflective surface on the South-facing side of the hotel. This model shows how a caustic surface is generated in the pool area around the ...

Gravitational Lensing

This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I.

Under-Deposit Corrosion

In this model, the effect of corrosion product on galvanic corrosion between a magnesium alloy (AE44) and mild steel in contact with brine solution is presented, wherein deformed boundaries due to both deposition of corrosion product as well as dissolution of magnesium are considered. The transport of Mg2+ ions generated at the magnesium surface and OH- ions generated at the mild steel surface ...

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 taken from NAFEMS Understanding Non-Linear Finite Analysis Through Illustrative Benchmarks. The load ...

Self-Consistent Schrödinger-Poisson Results for a GaAs Nanowire

This benchmark model simulates a GaAs nanowire using the self-consistent Schrödinger-Poisson theory to compute the electron density and the confining potential profiles. The predefined Schrödinger-Poisson multiphysics coupling feature is combined with the dedicated Schrödinger-Poisson study type to provide streamlined procedure for model setup and automated creation of self-consistent iterations ...

Prestress of Main Bearing Cap Bolts

This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced stiffness in the threaded part of the bolt is taken into account by a reduction of the stiffness of the material.
