Modifying Imported CAD Geometry with the Deformed Geometry Interface

When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or shape. But, in fact, you can modify the geometry that you've imported with some clever usage of the Deformed ...

Leaky Well

In layered sedimentary sequences confining units often sandwich viable reservoirs. If the confining units create less than perfect seals, fluids from an overlying reservoir can leak into the pumped reservoir below it. Often the pumping from the lower reservoir does not change flow in the unpumped one above. In these cases the leakage through the imperfect confining unit can be modeled as a ...

Electric Heating in a Busbar, Modeled with LiveLink for SolidWorks

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

Optimization of a Tuning Fork, Modeled with LiveLink for Inventor

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Numerical modeling of glacier flow

Glacier ice is generally treated as an incompressible, heat-conducting non-Newtonian fluid. The viscosity of ice depends on temperature and on the state of deformation. In the case of Storglaciären, however, the influence of temperature-dependent viscosity on the general flow field of the glacier is small. With COMSOL Multiphysics, it is relatively easy to verify that neglecting this ...

Double Pipe Heat Exchanger

Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow through the system, the material properties of both change with the varying temperature. The model uses the ...

Lombardi Surface Mobility in a Semiconductor

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 Matthiessen’s rule. This model demonstrates how to use the Lombardi surface mobility model for the electron ...
