Go to All Programs, select COMSOL 5.2a and then Client-Server, and select COMSOL Multiphysics 5.2a Server. If starting the COMSOL Multiphysics server from a terminal window in Windows, use the command <COMSOL Multiphysics installation directory>\bin\win64\comsolmphserver.exe.

•	On Mac OS X, use the COMSOL Multiphysics Server application, or if you connect to Mac OS X from another computer, use the comsol mphserver command in the terminal window.

Initializing the COMSOL Multiphysics Server

The first time you start a COMSOL Multiphysics server on a computer, you are asked for a username and password. By default, your username and a hashed password is stored on your computer’s hard drive. You can avoid storing your username and password on disk by providing the -passwd nostore target option to the COMSOL Multiphysics server command. When the COMSOL Multiphysics server is started, the server displays the port number. The server also displays a message each time you log in from a client.
