This tutorial models a DC glow discharge by solving fluid-type plasma equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is ... Mehr lesen
This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D Inventor® geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL Multiphysics ... Mehr lesen
A spherical hydrophone consisting of a PZT ceramic, a coating material, and a cable is modeled in 2D axisymmetry. The Receiving Voltage Sensitivity (RVS) is computed for an incident plane wave and compared to an analytical solution from the reference for an ideal spherical hydrophone. ... Mehr lesen
This application shows how mass transfer out from a thin 3D domain can be approximated using a 2D component with the domain feature Out-of-Plane Flux. This feature is useful when the concentration gradient in the out-of-plane direction (along the thickness) is small, and decreasing the ... Mehr lesen
A 3D silicon waveguide is set up with rib and slot configurations. The meshing includes physics-controlled mesh, with the number of longitudinal mesh elements set to 50 to visualize the wave oscillation. The detailed discussion of the model setup is discussed in the blog post: "Silicon ... Mehr lesen
This tutorial model solves for an inductively coupled plasma reactor in a mixture of SF6/argon. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Mehr lesen
Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using ... Mehr lesen
This model is a benchmark model for the Slip Flow interface. It is based on both analytic and numeric calculations. Air at atmospheric pressure flows through a conducting micro-channel connecting two reservoirs maintained at different temperatures. A flow between the two reservoirs ... Mehr lesen
The thin low permittivity gap boundary condition is meant to approximate a thin layer of material with low relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the thin low permittivity gap ... Mehr lesen
This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface. The exterior acoustics are modeled using the Pressure ... Mehr lesen
