Description
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 in the software by the user at that time, are checked out. This licensing design allows different features to be bundled into different product licenses that better fit customer needs without requiring customers to overpay for features that they don't need.
Example
When one feature/increment is checked out by a user, it locks all other features associated with that product license from being checked out by another user. For example: In the product pictures above, if User A opens mechanical and checks out the "ansys" increment, User B will not be able to checkout "dsdxm", even though that feature is not explicitly checked out by User A.
Solution
License File Location
The default name and location of the installed license file on the license server is:
C:\Program Files\ANSYS Inc\Shared Files\Licensing\license_files\ansyslmd.lic"
Example License File
SERVER acmeco-licsrv 690daec9 1055
VENDOR ansyslmd PORT=1056
USE_SERVER
# 1. ANSYS Mechanical Enterprise: 5 task(s) Permanent with TECS expiring 08-Jan-2023 Customer # 123456 Borrowable
INCREMENT ansys ansyslmd 2023.0108 08-jan-2023 5 8C59A481BA90 \
VENDOR_STRING=customer:00123456 SUPERSEDE ISSUER=SIEBEL \
