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.
Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Read More
In this example, monotonic and cyclic triaxial tests are simulated using the Hardening Soil Small Strain material model. The model captures the effects of small strain stiffness and hysteresis under cyclic loading. The stress-strain relationship matches the hyperbolic curve reported in ... Read More
This app demonstrates: Light theme This app allows you to evaluate cross-section data for a wide range of American and European standard beams. Given a set of forces and moments acting on the section, you can also compute a detailed stress distribution. Calculated cross-section data ... Read More
FEM simulation can be used to obtain a SAW velocity and some related parameters (squared electromechanical coupling coefficient, reflectivity, etc.) for different typical configurations. Such parameters are input data for various analytical and semi-analytical methods of SAW device ... Read More
For slender structures, buckling is a catastrophic instability if the service load is above the critical limit. For such structures, it can be important to study the behavior of the structure beyond the critical buckling load, which is known as postbuckling analysis. Tracing the ... Read More
This model studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. Read More
This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... Read More
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ... Read More
This conceptual example shows how to calculate critical points in models with contact. The model consists of two contacting arches modeled with the Shell interface. The contact problem is solved using the penalty method. The upper arch is loaded with displacement controlled edge loads ... Read More
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Read More
