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 entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... Read More
The example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. ... Read More
Periodic microstructures are frequently found in composite materials, metallic foams, and sandwich structures. They can be described by a unit cell repeated along the three Cartesian directions. This app computes homogenized material properties of various periodic microstructures and ... Read More
This tutorial demonstrates how to compute the response of an ultrasonic car parking sensor transducer coupling Pressure Acoustics, Frequency Domain, Solid Mechanics, and Piezoelectric Materials. The far-field radiation pattern of the transducer is then used as a source for a Ray ... Read More
This example demonstrates the wrinkling phenomenon in a thin sheet stretched uniaxially. The modified membrane theory, which incorporates the wrinkling model, ensures noncompressive principal stresses in the wrinkled region. The analytical results are compared to the numerical results. 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
When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... Read More
Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ... Read More
This small tutorial model shows how to set up a model with a solid mechanics and a pressure acoustics domain including a common perfectly matched layer (PML). The PML is used to model an open or infinite domain for both the elastic waves and the pressure waves. Three configurations of ... Read More
This model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... Read More
