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.
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
Liquid-liquid extraction is a process used to separate or transfer species between two immiscible liquids. Transfer of species from one phase to the other is driven by a difference in relative solubility. In this model a water filled extraction column is studied. Oil droplets containing ... Read More
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the Lithium-Ion Battery interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... Read More
Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... Read More
It is possible to realize a narrowband bandpass filter using cascaded microstrip coupled lines. In this example, a design composed of cascaded microstrip lines, each approximately a half wave length in size at the resonant frequency, is analyzed. The model is solved for the S-parameters ...

An antenna array is a group of radiating elements. By controlling the phase and magnitude of the input signal assigned to each antenna element and the number of array elements, the radiation pattern can be steered in a desired direction with a preferred level of gain. In this example, a ... Read More
This model of a two-story house can be used to examine a contaminant leak and the subsequent contaminant dispersion that occurs due to convection and diffusion. Airflow and recirculation within the home are dependent on vent placement, and flow velocity may also vary at each vent. ... Read More
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Read More
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ... Read More
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Read More
