Comsol Multiphysics 3.5a Free Download [patched] (2025-2026)

Many universities have campus-wide licenses. If you have a .edu email address, you can often get a 6- or 12-month full-featured license for less than $100. Alternatively, COMSOL offers a free "Student" version with limited mesh sizes (usually ~1000 degrees of freedom) which is perfect for homework.
