I understand you're looking for information about downloading COMSOL Multiphysics. However, I need to provide an important clarification upfront: While COMSOL no longer offers 35a on their
COMSOL Multiphysics is a commercial proprietary software — there is no legitimate "free download" of version 3.5a or any other full version. What you may find on third-party websites claiming to offer "free" downloads are almost always:
Some researchers need to reproduce models from old papers. Many academic theses from 2006-2010 used .mph files specific to version 3.5a. Newer versions cannot open these legacy files without significant conversion errors. Thus, they need the exact installer. The physics haven't changed that much; the GUI has
If you must use 3.5a (e.g., to run old models or match published results):
