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 ...

Transport and Reaction in a Catalyst in 3D

Consider the study of a mass balance of a diluted species in air, for example, a pollutant in an exhaust stream. The model’s aim is to calculate the concentration profile of this species, which is decomposed by a catalyst present on the surface of a porous supporting structure. In a first step, you solve the velocity field for the solution assuming that the diluted pollutant has no influence ...

The Blasius Boundary Layer

The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally transitions to a fully turbulent boundary layer. Due to its fundamental importance, this type of flow has ...

Optimization of a Tuning Fork, Modeled with LiveLink for Solid Edge

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

Ion Funnel

An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, allowing mixtures of ionized gases to be separated and analyzed while minimizing losses. This model ...

Modeling a Distributed Model of Thermal Microactuator on a Cluster

A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing functionality in COMSOL from COMSOL Desktop and use it to submit a batch job to a cluster through a job scheduler. The ...

Gate Valve in Pipe Branch

A gate valve in a piping branch point is simulated using high viscosity in the gate itself. A parametric run varies gate position from 100% open to fully closed

Electric Heating in a Busbar, Modeled with LiveLink for Inventor

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Inventor 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 Pro/ENGINEER

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