Ansys elastic licensing

Overview of Elastic Licensing

Ansys Elastic Licensing is a "pay-per-use" licensing system that enables hourly-based licensing of virtually every Ansys product through a single product offering called Ansys Elastic Unit (AEU). Ansys Elastic Licensing complements other licensing solutions from Ansys by providing you with on-demand access to core portfolio of pre-post, solver, and HPC simulation solutions. You only pay for what you use, allowing you to efficiently meet fluctuating licensing demands throughout the year, while accommodating high usage periods associated with critical new projects. You simply buy a number of AEUs and from this "pool" as you consume them. Each Ansys product consumes a number of these AEUs per hour.

The page provide the guidelines on setting Lumerical to obtain the license from the Ansys elastic license.
