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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.


Modeling Phase Change with Hysteresis

This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "[Thermal Modeling of Phase-Change Materials with Hysteresis](https://www.comsol.com/blogs/thermal-modeling-of-phase-change-materials-with-hysteresis/)".

Beam Subjected to Traveling Load

As an example of how to build an app using the Application Builder, this application simulates the transient response of a beam, or bridge, that is placed on several equidistant supports and is subjected to a traveling load. The purpose of the Beam Subjected to Traveling Load app is to analyze the structural response of a bridge when vehicles pass over it. Many of the bridge's parameters can be ...

Setting up Periodic Heat Loads for Simulation

This example exemplifies how to model applications subjected to periodic heat loads. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "[Modeling a Periodic Heat Load](https://www.comsol.com/blogs/modeling-a-periodic-heat-load/)".

Helical Static Mixer

Helical static mixers are often used to mix monomers and initiators that then react during a polymerization process. The purpose of the Helical Static Mixer application is to demonstrate this mixing process as well as the use of parts and parameterized geometries when building apps. The concentration field is included in the analysis in order to compute the extent of mixing between two streams ...

Interpolation between points using a COMSOL App

This App will fit a surface through a set of points using Radial Basis Functions and will write out a COMSOL-format file of a smooth NURBS surface that passes through all of the points. The function describing the surface can also be written to a text file. The point data is read in from comma-delimited file and thin-plate spline radial basis functions are used to fit the surface. Up to 5000 ...

Simulating Action Potential with the Hodgkin-Huxley Model

This app allows you to simulate the action potential in a cell's membrane using the Hodgkin-Huxley model. As it is presented in the form of a simulation app, you can change the input parameters for potential, conductance, and membrane capacitance to study their effects on the dynamics of the system. A more detailed description of the phenomenon, and the modeling process, can be seen in the ...

Modelling of the Chemo–Rheological Behaviour of Thermosetting Polymer Nanocomposites

Nanocomposites based on polymers and inorganic layered clays have been the subject of increased interest in the scientific and industrial community due to their potential and promising properties. Indeed, a small amount of clay may produce enhanced properties due to the large contact area between the polymer and clay through a nanoscaled hybrid. In addition, the layered structure of clay with ...

Thermal Curing Simulation

This example exemplifies how to model thermal curing using the base package of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Modeling the Thermal Curing Process]( https://www.comsol.com/blogs/modeling-the-thermal-curing-process/)".

Image Import: Homogenized Pore Scale Flow and Thermal Conduction

You can now use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM), computed tomography (CT), or magnetic resonance imaging (MRI). An important application of image import is for easy computation of equivalent volume-averaged ...

Modeling the Behavior of a Thermostat

This example exemplifies how to model applications using the *Events* Interface where a thermostat is sumlated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Implementing a Thermostat with the Events Interface](https://www.comsol.com/blogs/implementing-a-thermostat-with-the-events-interface/)".
