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.
Piezoelectric microblowers are compact, lightweight air pumps with varying applications including electronics cooling and airflow related medical devices. The device consists of a PZT-brass diaphragm and a specially designed housing including a pumping chamber, air inlet and outlet ... Read More
This tutorial demonstrates how to create domains for modeling inside and outside of an imported CAD assembly. You will also learn how to use the defeaturing tools for deleting details from the imported geometry. Read More
This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... Read More
KOH(aq), an alkali metal hydroxide solution, is widely used in anisotropic wet etching technology and is one of the most commonly utilized solutions for micromachining silicon wafers. Anisotropic etching refers to a process where the etching rate varies in different directions, primarily ... Read More
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Read More
A line array of eleven spherical hydrophones embedded in a neoprene coating is modeled in 3D. The sensitivity of the array is analyzed with regard to varying angles of incidence of the background pressure field. The array directivity function is computed and compared to the analytical ... Read More
The Dzhanibekov effect, also called the intermediate axis theorem or tennis racket theorem, describes the behavior of a rigid body with three distinct principal moments of inertia. This simulation app can be used to test the Dzhanibekov effect in three different geometries, including a ... 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
Example for a geometry sequence to create a ship hull using Loft. The different cross sections are defined using Dimensions and Constraints. Read More
This model demonstrates how to use a space-time formulation to optimize a heating profile over time. Get an overview in the accompanying blog post Equation-Based Modeling with a Space-Time Discretization. Read More
