The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
The heat distribution in a hollow pipe, whose ends are held at two different temperatures, is studied. The outside surface is assumed to be thermally isolated and the inner surfaces have radiation boundary conditions. The role of convection in the heat transfer is taken to be ... Read More
This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. Read More
This tutorial simulates a small vibrating hemispherical particle in water. The particle has a radius of 1 mm and is oscillating in the axial direction at a frequency of 50 kHz. The vibrations induce acoustic waves in the fluid. The example demonstrates how to set up a thermoviscous ... Read More
Just like optical lenses focus light, electric and magnetic lenses can be used for focusing beams of charged particles. This COMSOL Multiphysics model shows the path of B5+ ions passing through a focusing system of three magnetic quadrupoles. Each of the quadropoles focus the beam of ... Read More
In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ... Read More
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 ... Read More
This tutorial model is of a micro perforated plate (also known as MPP) backed by a vibrating structure. This is a typical configuration in, for example, a MEMS microphone. The vibrating structure is not modeled explicitly, but just assigned a vibration velocity. The vibrating structure ... Read More
The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. The secondary coil is modeled using a homogenized approach which does not explicitly consider each turn ... Read More
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... Read More
This example models the temperature profile in a liquid-cooled prismatic battery pack during a high-rate charge. The pack consists of 16 prismatic battery cells connected by busbars, placed on an aluminum plate containing four cooling channels. The battery pack is assumed to have two ... Read More
