DSLS (Dassault Systèmes License Server) is a licensing system developed by Dassault Systèmes that provides such benefits as:

  • License usage statistics, debugging, and simple UI to administer and view statistics.
  • Licenses are bound to expiration date rather than product version.
  • Nodelock, floating, and managed licensing options.

DSLS and modeling tools compatibility

You must choose the DSLS version compatible with the modeling tool version you use.
