In this multibody dynamics model of a simple counterweight trebuchet, a parametric sweep is used to study throwing distance as function of the sling length. For more details on performing a multibody analysis of a counterweight trebuchet, see this blog post: What Is the Physics Behind a ... En savoir plus
This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... En savoir plus
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... En savoir plus
This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses ... En savoir plus
This model is used in the blog post "Why Do Golf Balls Have Dimples?". The trajectory of a golf ball is compared to the trajectory of a smooth ball using the Events interface and a system of ODEs in a 0D component. En savoir plus
This model simulates a beam of light being split into components of different frequencies when passing through a medium where the refractive index depends on frequency. COMSOL-wise, the model showcases two important technical aspects: A user-defined implementation of the frequency ... En savoir plus
Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care ... En savoir plus
This example demonstrates an app that utilizes the LiveLink™ interface for SOLIDWORKS® to run simulations on CAD designs. En savoir plus
This model demonstrate how to simulate ray tracing in a pinhole camera viewing a solar eclipse. To keep the model dimensions in check, the Sun and Moon are approximated using planar discs with the appropriate angular size (~0.5 degree) relative to the pinhole. In this example, the ...

In this model, the electrical performance of a W-band waveguide to microstrip line transition (WMLT) is investigated. A standard WR10 waveguide is used and the transition from waveguide to microstrip line is achieved by utilizing the longitudinal probe (also known as E-plane probe) ... En savoir plus
