If you share what specific physics or application you're working on (e.g., heat transfer, MEMS, acoustics), I can point you to the best free tool or trial route.
If you’d like a version focused only on technical features of COMSOL 3.5a (without the download request), or help finding open-source alternatives, let me know. comsol multiphysics 35a free download best
COMSOL Multiphysics 3.5a is a legacy version of the famous finite element analysis (FEA) software. While the current version is , many researchers still look for 3.5a due to its unique compatibility with older models or its specific interface with legacy MATLAB toolboxes.
