COMSOL Multiphysics Client-Server Architecture
The COMSOL Multiphysics client-server architecture lets you access the COMSOL Multiphysics server — the computational engine in COMSOL Multiphysics — as a separate process. The COMSOL Multiphysics server is a single user server allowing multiple connections by the same user.
You must have a floating network license (FNL) to run a COMSOL Multiphysics server and a COMSOL Multiphysics client on separate computers. Any valid COMSOL Multiphysics license is sufficient to run the Multiphysics client and the Multiphysics server on the same computer.
To start the COMSOL Multiphysics server under windows, just click COMSOL Multiphysics Server in the Client-Server folder under your COMSOL Multiphysics installation on the Start menu. On Linux and Mac, type the command comsol mphserver to start the COMSOL Multiphysics server.
For more options for starting the COMSOL Multiphysics server, see the section The COMSOL Commands for your platform. Also see the section Running COMSOL Multiphysics in Client-Server Mode for detailed general information about client-server options.
