Streamers are transient filamentary electric discharges that can develop in a nonconducting background in the presence of an intense electric field. These discharges can attain high electron number density and consequently a high concentration of chemical active species that are relevant ... Mehr lesen
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... Mehr lesen
This conceptual model analyzes the influence of leaks on the acoustic response of an earbud speaker placed in an ear-canal-like geometry. Built-in impedance models are used to capture the effects of a perforated plate in front of the speaker, skin impedance, and ear drum impedance. The ... Mehr lesen
These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between volumetric conductors. Additional models show how to use impedance and transition boundary conditions to model the conductors, instead of ... Mehr lesen
This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established ... Mehr lesen
Dieses Modell zeigt einen Ansatz zur Ermittlung einer Breitband-Impulsantwort durch Kombination von Raytracing- und Finite-Elemente-Methoden. Die Kombination erfolgt vollständig in COMSOL® unter Verwendung idealisierter Filter. In diesem Beispiel werden die Simulationsergebnisse ... Mehr lesen
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... Mehr lesen
Modeling the penetration of a needle into soft materials, such as gelatin, involves several complex mechanical challenges, including large deformations, high friction, contact forces, and material failure. This example simulates the needle insertion process into tissue-like materials ... Mehr lesen
Optical computing has been a promising paradigm alternative to the current electronic computers. This model simulates an optical 4-by-4 unitary matrix multiplication device based on a network of six Mach–Zehnder interferometers (MZIs). A more detailed description of this model can be ... Mehr lesen
In this model, an eigenfrequency analysis is performed to give a bandgap analysis of a 1D multilayer photonic crystal extending to infinity in +/- y direction. We perform the bandgap analysis for three different cases of material properties, as discussed in Chapter 4 of Ref. 1. Case ... Mehr lesen
