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.
Uncertainty Quantification is used to study the effect of manufacturing variation on the performance of 2D Solidly Mounted Resonator (2D SMR). This tutorial shows how resonant frequency is effected by thickness variations of the piezoelectric layer and the Bragg reflector layers. The ... Read More
Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... Read More
Chemical mechanical polishing (CMP) is a crucial technique for surface planarization, widely used in semiconductor fabrication and optical device manufacturing. This model simulates the flow field within the CMP retaining ring and tracks the motion of abrasive particles carried by the ... Read More
A radio frequency quadrupole ion trap utilizes a radio frequency quadrupole (RFQ) in order to trap an ion beam. A continuous high energy ion beam is first cooled and converted into a spatially confined bunch, which can then be released with minimal heating of the beam. The device is also ... 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
This example of a dipole antenna array demonstrates a cost-effective analysis using the Boundary Element Method (BEM). When dealing with a large array made of metallic radiators, the Finite Element Method (FEM) would necessitate greater computational resources. The simulation results ... Read More
Tutorial model investigating a set of two competing reactions. The model demonstrates the natural modeling strategy for reaction engineering in COMSOL Multiphysics®. That is, how to go from chemical equations to space-dependent models of reacting flow with a minimum of work. Read More
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Intended as a tool for early proof of concept in capacitive touchscreen device development, the Touchscreen Simulator app evaluates a simulated capacitance matrix as well as the electric field norm. The app computes the capacitance matrix of a touchscreen in the presence of a human ... Read More
Compliant mechanisms are attractive due to their simplicity, owing to their lack of hinges. In this model we show how to design a set of compliant pliers using topology optimization. The resulting design is post-processed using shape optimization, where the maximum stress is constrained ... Read More
