Electric Heating in a Busbar, Modeled with LiveLink for Solid Edge

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.

Image Import: Homogenized Pore Scale Flow and Thermal Conduction

You can now use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM), computed tomography (CT), or magnetic resonance imaging (MRI). An important application of image import is for easy computation of equivalent volume-averaged ...

How to Use Contour Line in Geometry

This presentation gives instructions on how to export a Contour Plot (single line), re-import it as an Interpolation Curve on a Work Plane in the Geometry, extrude the Work Plane, then Convert to Solid to create two domains separated by the new surface.

Two-port Piezoelectric SAW Device

This tutorial shows how to model surface acoustic waves in time domain. The 3D modeling geometry represents a 128 degree YX-cut lithium niobate substrate. The SAW device has two ports. The metallic electrodes are modeled as perfect conductors using boundary conditions. The geometric dimensions such as size of substrate, the gap between the ports and the number of inter-digitated electrodes (IDTs) ...

Electrocoating of a Car Door

This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to describe the charge transport in the electrolyte. The model is in 3D and uses an imported CAD geometry.

Lumped Receiver Connected to Test Set-up with an 0.4-cc Coupler - new

In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube inlet. The response at the measurement microphone in the coupler as well as the electric input impedance to the ...

Loudspeaker Suspension

In this model, the resistance and compliance of the suspension in the Loudspeaker Driver model are computed using a purely mechanical analysis.

Ground Heat Recovery for Floor Heating - new

Geothermal heating is an environmentally friendly and energy efficient method to supply newer and well insulated houses with heat. The investment costs are higher than for gas or oil heating so there is a need to investigate the possibilities of arranging heat collectors in the subsurface. This model compares three different patterns embedded in the subsurface with typical thermal properties of ...
