SEIR Model for the COVID-19 Epidemic

Tutorial example of a Erlang SEIR model for the epidemic of COVID-19. The model is validated against data from China, Sweden, and the US. Parametric estimation is done using the reported deaths over time. The tutorial investigates the impact of social distancing on the progress of the ... Читать дальше

Optimizing Coils

Several different approaches to optimizing a ten-turn axisymmetric coil are presented. First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a ... Читать дальше

Geometry optimization of a 3D complex-shaped coil for induction heating

The model features the optimization of the geometry of a complex-shaped coil similar to those for induction heating applications. The geometry if fully built and parametrized in COMSOL Multiphysics (taking advantage of Geometry Parts; geometrical construction requires Design Module). The ... Читать дальше

Impedance Tube Parameter Estimation with Data Generation

Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound inlulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two ... Читать дальше

Optimization of a Tesla Microvalve

This model performs a topological optimization for a Tesla microvalve. A Tesla microvalve inhibits backwards flow using friction forces rather than moving parts. The design can be optimized by distributing a specific amount of material within the modeling domain. The goal is to maximize ... Читать дальше

Sub-Component Lumping in Acoustics Using the Impedance Boundary Condition

This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Читать дальше

This presentation shows how to use the Optimization Module to fit a material model curve to experimental data. It is based on the hyperelastic Mooney-Rivlin material model example given in the Structural Mechanics users guide. Читать дальше

Topology Optimization and Verification of an Acoustic Mode in a 2D Room

This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ...
