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.
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Read More
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... Read More
A surface mount resistor is subjected to thermal cycling. The difference in the thermal expansion of different materials will introduce stresses in the structure. The solder which connects the resistor with the printed circuit board is seen as the weakest link in the assembly. It ... Read More
This app demonstrates the following: Selecting predefined or user-defined materials User option to switch between laminar flow or turbulent flow Changing boundary conditions using methods Visualizing temperature dependent material properties as graph plots User option to set the solver ...

This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
This tutorial models an ICP reactor by solving plasma fluid type equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is coupled ... Read More
This tutorial demonstrates the Lumped Battery interface for modeling capacity loss in a battery. A set of lumped parameters are used to describe the capacity loss that occurs due to parasitic reactions in the battery, assuming no knowledge of the internal structure or design of the ... Read More
Differentially pumped vacuum systems use a small orifice or tube to connect two parts of a vacuum system that are at very different pressures. Such systems are necessary when processes run at higher pressures and are monitored by detectors that require UHV for operation. In this model, ... Read More
This tutorial illustrates how to use the Uncertainty Quantification (UQ) functionality to answer questions regarding sensitivity and reliability of a flow reactor with thermal decomposition. The tutorial investigates what uncertainties in parameters dominates the survival of a nutrient ... Read More
This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... Read More
