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 tutorial minimizes the mass of a bracket that is synchronized from PTC Creo Parametric™ via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of ... Read More
The AC/DC magnetic interfaces support material models defined in external C code. You can access external material functions, written in C code, which have been compiled into a shared library. By writing a wrapper function in C code, you can also use material functions written in another ... Read More
This tutorial introduces a workflow typical of creating geometry for simulation by using Sketch mode to draw complex shapes. Follow the step-by-step instructions to draw the geometry for the analysis of a light bulb. The physics setup is described in the model Free Convection in a Light ... Read More
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Read More
This model shows how to model a simple Metal–Insulator–Metal (MIM) diode. The two metal electrodes are defined on each side using the Metal Contact feature. Two studies were performed: one without quantum tunneling across the potential barrier and the other including it, using the WKB ... Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SOLIDWORKS® via the LiveLink™ interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
One of the possible formats when working with scanned data is images for the slices of an MRI or CT scan. This is an example with images from the cross sections of the different levels of a human head. In short, the procedure includes creating curve objects of each of the images using ... 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
The flow around the Eppler 387 airfoil is computed with the SST turbulence model both with and without the transition model. The reuslts are compared with experimental values. Read More
In nuclear fusion reactors, the conducting fluid, such as the fusion plasma and the liquid metal in the reactor blanket, will interact with the background magnetic field. This phenomenon is referred to as magnetohydrodynamics (MHD). The electromagnetic field and fluid flow are fully ... Read More
