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 illustrates how to combine different Creep material models. Here a Norton–Bailey model (primary creep) is combined with a Norton model (secondary creep). This example is a continuation of the model thermally induced creep. Read More
One method of creating spring-like structures or inducing curvature in thin structures is to plate them to substrates that are under the influence of residual stresses. The plating process can control this stress even for similar materials. One such device is the electrostatically ... Read More
This model shows how to control the position of the base of an inverted pendulum to keep it vertical. The control is performed using a PID controller in Simulink®. The position of the base is constrained within specified limits, and an external force is applied at the base to keep it ... Read More
This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface. The exterior acoustics are modeled using the Pressure ... Read More
This model demonstrates topology optimization of a 2D heat exchanger with laminar flow. The flow is pressure driven and the objective is to maximize the heat transfer. The density method is used with the (now) classical approach of a single design variable and two flow interfaces. ... Read More
This model computes the temperature distribution in a battery pack that is in use at a specified power. The current is controlled in Simulink® to ensure constant power during usage. Read More
This local demo database for the Model Manager contains an imported copy of the Application Library models in COMSOL Multiphysics® version 6.0 and above. You can add this database from COMSOL Multiphysics® by selecting Download Demo Database for Model Manager from the ... Read More
The four-point bending test is a conventional test method used to test the mechanical properties of materials subjected to bending. It is a reliability test used for semiconductor packaging and assembly. This model demonstrates the stress analysis of an IGBT module subjected to a four ... Read More
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Read More
