The Magnus Effect
The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every FIFA World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses ... En savoir plus
Thermal Impact of a Borehole Heat Exchanger Array
This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... En savoir plus
Preconditioning (PRE) of Surface Mount Devices (SMDs) for testing
Prior to the reliability testing, surface mound devices (SMDs) are required to go through a preconditioning process, which represents the effects of storage and the typical reflow operation in the following board assembly process. During the preconditioning process, test samples usually ... En savoir plus
Wheel Rim Defeaturing Tutorial Series
This tutorial series demonstrates three different approaches to remove small geometric entities from an imported 3D CAD geometry of a wheel rim: the Repair operation, the Defeaturing tools, and the Remove Details operation. Use Repair to automatically find and remove small entities ... En savoir plus
Switched Reluctance Motor
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact so as to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and the rotor being ... En savoir plus
App with CAD Import and Selections
This app simulates a micromixer based on an imported CAD geometry. The app shows how you can use the Application Builder to build an app that can handle CAD import and let the user interactively select boundary conditions. The app shows how this can be done without any programming using ... En savoir plus
Axial Homopolar Induction Bearing in 3D
This model illustrates the working principle of an axial homopolar induction bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that ... En savoir plus
Demonstration of Global Equations to Introduce a Goal-Seeking Equation
Two approaches are demonstrated to introduce a goal-seeking Global Equation into a COMSOL Multiphysics® model. This Global Equation acts to adjust a single input of the model such that any single scalar output of the model takes on a desired target value, or goal. Learn more in ... En savoir plus
Computing Projected Area
This model presents a way to compute projected area using the Surface-to-Surface Radiation interface of the Heat Transfer Module. By computing illuminated area from a set of directions on a discretized sphere, it is possible to interpolate the projected area onto any angle of incidence. ... En savoir plus
Transient Model of Signal Propagation
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... En savoir plus
