Several years ago, I wrote an article on using Elmer to solve complicated physics problems. Elmer has progressed quite a bit since then, so I thought it would be worth taking a fresh look at this simulation software (https://www.csc.fi/web/elmer). The first step is to install Elmer on your system. It may exist within your package management system, but those are likely older versions. If you are running a Debian-based system, you can get the latest versions by adding the Elmer repository to APT and installing it from there.
