This lesson focuses on understanding the contents of the Ansys-issued license file, which is a specially formatted and encrypted text file that contains information about the machine on which the license daemons will run, the vendor daemon name, and a list of increments for each feature in the tool set. We will also discuss the product to feature mapping and its available file formats. Lastly, we will discuss the Ansys installers and different packages available for the user to install.
