A Transport Problem

A transport problem, modeling stationary transport in one direction, with a discontinuous solution is solved to illustrate the effect of streamline diffusion. A pure stationary transport problems contains a convective term only. This means that oscillations and instabilities from the numerical method are some factors that need to be addressed. Streamline diffusion stabilizes oscillations ...

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 SolidWorks

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

Thermal Performances of Roller Shutters

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Thick Wall Cylinder Benchmark Problem

A thick wall cylinder is exposed to both internal and external pressure and thermal load. The model is both plane and axisymmetric. The results are compared to the analytic solution.

Perforated Well

Analysis of fluid flow into wells often begins with the assumption that the intake fluid is uniform along the entire length of wellbore. This assumption runs into trouble when applied to the modeling of perforated wells. When these wells are emplaced, the deep bore hole is lined by impermeable materials. Later a machine pierces the lining intake fluids in the productive reservoir zones and ...

1D Step Bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

1D Plane Slider bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

Reaction Chain

This model describes the simultaneous transport of three solutes in a chain reaction within a variably saturated flow field. Involved are advection, dispersion, sorption, biodegradation, decay, and volatilization. The parent solute decays to a daughter product, which generates another tracked daughter. Built on the flow field described in Sorbing Solute, the transport scenario described here ...

Inclined Screen

This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution.
