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.
This tutorial utilizes the Particle Beam feature to examine the performance of a high-precision spectrometer. An ion beam is subjected to electric and magnetic forces, and only a fraction of the incoming beam is transmitted to the detector. The Particle Counter feature is used to compute ... Read More
One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... Read More
The model studies optimal material distribution in a hook, which is symmetric about the z plane and consists of a linear elastic material, structural steel. It is subjected to two distributed edge load cases: One at the tip of the hook and one along its lower inner curve. The geometry is ... Read More
Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... Read More
Many applications involve simulating the electromagnetic behavior of relatively thin material in voluminous domains. To save computer memory and processing time, the thin materials can be treated differently by resolving them with 3D meshes. Here, the modeling domain is a box filled ... Read More
This model simulates the dynamics of the shock absorber used in a landing gear mechanism of an aircraft. It analyses the stresses, as well as the heat generated in the landing gear components due to the energy dissipated in the shock absorber. A prismatic joint, with spring and damper, ... Read More
This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin Layer boundary condition with the thermally thick option is used to avoid ... Read More
This model is an introduction to defining and verifying a satellite orbit, and computing the solar, albedo, and Earth infrared thermal loads. A 1U CubeSat is in a circular orbit at 400km altitude, inclination of 50°, and longitude of ascending node of 0°. The satellite is rotating slowly ... Read More
An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... Read More
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ... Read More
