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 app demonstrates the following: Multiple tabs in the ribbon Geometry parts and parameterized geometries Parts and cumulative selections can be used to automatically set domain and boundary settings in the embedded model Adding or removing geometry parts with different geometrical ... Read More
Unwanted electrical arcing poses significant risks to the reliability and safety of electrical and electronic systems. To enhance predictive capabilities and deepen understanding of arc behavior, we present a comprehensive numerical model for simulating transient arc discharge phenomena ... Read More
Thermal management of a battery pack is simulated considering two scenarios, air (natural convection) and phase change material (PCM) in the gap between the batteries. The PCM considered is a composite material of paraffin wax and graphite additive. Graphite is typically added for ... Read More
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different ... Read More
This app demonstrates the following: How an app can be used as a teaching tool An 8 question multiple choice quiz where the answers can be sent to the grader by email This app calculates the equilibrium compositions in gas phase conversion of ethylene to ethanol. It allows you to ... Read More
This example shows how to image the interior permittivity of a box by applying a potential difference on the boundaries of the box. The result is a surface charge density that depends on the permittivity of the medium inside the box. Read about this tutorial model in our blog post "The ... Read More
In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack. This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where energy is supplied through heating tubes to drive ... Read More
This example simulates the temperature dynamics in cylindrical battery, initially at room temperature, after being placed in an oven. As the temperature increases, various exothermal decomposition reactions are activated, which in turn result in further heating of the battery. Read More
This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... 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
