  • CPU-locked Single User License (CPU): This license type allows you to install and run COMSOL Multiphysics on one computer. You can use all the modules that you have purchased with this license type.



  • Named Single User License (NSL): This license type allows you to install and run COMSOL Multiphysics on up to four computers, but only one at a time. You can use all the modules that you have purchased with this license type.



  • Floating Network License (FNL): This license type allows you to install and run COMSOL Multiphysics on any number of computers on a local area network (LAN), but only a limited number of concurrent users. You can use all the modules that you have purchased with this license type.



  • Class Kit License (CKL): This license type allows you to install and run COMSOL Multiphysics on any number of computers in a classroom or lab setting, but only for teaching purposes. You can use all the modules that are included in the Class Kit License package.



  • COMSOL Server License (CSL): This license type allows you to install and run COMSOL Server on one computer on a LAN or WAN. You can use COMSOL Server to host and manage applications created with COMSOL Multiphysics and share them with other users via a web browser.



  • Academic Server License (ASL): This license type allows you to install and run COMSOL Server on one computer on a LAN or WAN, but only for academic research purposes. You can use COMSOL Server to host and manage applications created with COMSOL Multiphysics and share them with other users via a web browser.
