Use the comsol convertpre35a command to convert a directory with models made in any of the COMSOL Multiphysics versions 3.0–3.5 to COMSOL Multiphysics 3.5a. After converting such a model, it is possible to open it in later versions of COMSOL Multiphysics. This command requires that you have an installation of COMSOL Multiphysics 3.5a. To use the
comsol convertpre35a command, enter
