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 is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT also known as a receiver in some industries) which is a high performance miniature loudspeaker often used in hearing aids and other in-ear audio products. The model is set up using a linear frequency ... Read More
Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. The thermoelectric modules are a common application of thermoelectricity in cooling engineering. They consist of several thermoelectric legs ... Read More
The eddy currents in a conductive cylinder, generated from currents passing through a surrounding coil, are studied. The skin effect in the coil is also studied. Read More
This is a transient model of an electromagnetic plunger with stopper restricting the linear motion. The model consists of a magnetic core, nonmagnetic guider, multi-turn coil, nonmagnetic stopper/blocker, and magnetic plunger attached to the spring and damper at the base. The ... Read More
This model compares the numerical and analytical solutions for the capacitance matrix of two non-concentric spheres. It also illustrates the relation between the Maxwell capacitance matrix and the mutual capacitance matrix. Learn more about this model in the blog post "How to Calculate ... Read More
Electrical cables, also called transmission lines, are used everywhere in the modern world to transmit both power and data. These cables carry electromagnetic energy, but instead of dealing with the full complexity of the electromagnetic fields, they are more commonly classified ... Read More
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Read More
Electric impedance measurements are used for imaging and detection. Applications range from nondestructive testing and geophysical imaging to medical imaging. Several alternative techniques are shown to model such a system. One of them shows how to use conditional expressions to define ... Read More
Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps: The ... Read More
A model comparing the magnetization material models in time-dependent and frequency domain studies. Effective B-H curves are used for frequency domain. A linear relative permeability is included as reference. Read More
