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 example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... Read More
The elastic cantilever beam is one of the elementary structures used in MEMS designs. This model shows the bending of a cantilever beam under an applied electrostatic load. The model solves the deformation of the beam under an applied voltage. Read More
This verification model of nonisothermal turbulent flow over a flat plate compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Read More
In this example, triaxial and oedometer tests are simulated using the Hardening Soil material model. Both tests exhibit a hyperbolic stress–strain relationship. For the triaxial test, it is confirmed that the axial stress approaches the analytical failure stress asymptotically. In the ... Read More
Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... Read More
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Read More
In this example, monotonic and cyclic triaxial tests are simulated using the Hardening Soil Small Strain material model. The model captures the effects of small strain stiffness and hysteresis under cyclic loading. The stress-strain relationship matches the hyperbolic curve reported in ... Read More
Magnesium alloys are attractive alternatives as lightweight materials in various fields of engineering. Magnesium is however relatively non-noble and may suffer considerable galvanic corrosion when being used in conjunction with other metals, for instance when mounting an Mg alloy ... Read More
The present model example is based on Copper Deposition in a Trench model available in Electrodeposition Application Library. The nonuniform deposition along the trench surface leads to formation of a cavity/void. Since the Deformed Geometry interface cannot handle topological changes, ... Read More
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between the SOLIDWORKS® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric ... Read More
