Introduction

Recently, COMSOL has been updated from the revision 3.5a to 4.3a. The new revision has a different path to a problem set up, which is supposed to be easier. We refer a potential COMSOL user to the new COMSOL 4.3a user's guide that is available online. The new COMSOL revision is run with the command "comsol -ckl -np n", where n is a number of cpu's. Most of the old COMSOL *.mph files should still work with the new revision.
FileVideo tutorial (ogv format) for modeling of airfoil with comsol
This video explains how to model a simple airfoil in a wind tunnel with comsol. The video is in the Ogg video format and will play on Linux, Windows and Mac using the VLC player (http://www.videolan.org/vlc)

FileA crash course on comsol operation
This text gives a crash course on comsol operation with the exercise problem "Cooling of the Earth's core". Comsol is installed on a number of computers in our Astronomy Lab (room A107) in the Wright Centre. Comsol allows to numerically solve many multi-physics problems. Problem's set up and solution can be stored in a comsol *.mph file. In particular, the file Earth.mph below solves the problem presented in the introduction (Fig. 1). What you have to do is to download the mph file, start comsol, open the file, and click the equal sign on the main (upper) bar.
Fig. 1
The comsol file Earth.mph solves the problem of Earth's cooling in a 3D geometry (in fact, comsol figures out that the problem's set up is spherically symmetric, therefore internally it solves it in 1D). This figure shows the final distribution of temperature within the Earth. It is pleasant to find out that the surface temperature is above the freezing point. If you analyse the boundary conditions for this problem (look them up in the mph file), you will see that the comfortable final surface temperature is actually determined by the solar constant, i.e. by the solar luminosity and Earth's inhabitable distance from the Sun.

Download this file and open it in comsol, then click the equal sign in the main (upper) bar to solve the problem.
FileOverview
A slide set that provides an overview of example COMSOL projects we have done in the areas Electromagnetic Theory, Fluid Dynamics and Stellar Physics. These examples have been prepared by Dr Pavel Denissenkov.
Phys 422 projects with COMSOL 4.3a
This folder contains examples of the projects completed by Phys 422 students in the spring of 2015. These projects used the new revision of COMSOL 4.3a, therefore their description pages (*.pdf files) explain how to set up simple problems with the new revision.
