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/)".

Modeling Material Removal through Thermal Ablation

This example exemplifies how to model thermal ablation by taking into account material removal. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Modeling Thermal Ablation for Material Removal](https://www.comsol.com/blogs/modeling-thermal-ablation-for-material-removal/)".

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/)".

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 ...

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 ...

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/)".

Using Text Files to Automate Model Preprocessing

This example exemplifies how to set-up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Automate Model Preprocessing with the Application Builder](https://www.comsol.com/blogs/automate-model-preprocessing-with-the-application-builder/)".
