INFO - Understanding Ansys License Files (ansyslmd.lic)
Authored by Matthew Trachimowicz March 31st, 2022 852 views 0 likes KB1263241
Ansys software is based on a tiered licensing structure. When you purchase Ansys software, you purchase a license for a specific product(s), called a product license. Each product license is made up of one or more license features, also referred to as increments. See the example below taken from the Ansys Product to License Feature Mapping Document.
When opening and using an Ansys program, the product license isn't actually requested and checked out, instead only the license feature(s)/Increment(s) associated with the features/function being performed by the user at that time, are checked out.
This licensing design allows different features in your license to be used by different users at the same time vs one user consuming all features of an entire product license. This also allows Ansys to package different features into different product licenses that better fit customer needs without requiring customers to overpay for features that they don't need.
