abandoned/ghost license
a term used to describe a license that is reserved by a client that has disconnected and then reconnects under a new “client ID”, and as a result, checks out a new license and does not utilize the previous license reservation. This results in extra, unintended, license checkouts. The original reservation will be released after the License Disconnect Timeout Period. This is caused by a bug in the FlexNet code and can occur in several scenarios: A client disconnects and then reconnects from a new network adapter such as going from Ethernet to WiFi. A client disconnects and then reconnects after going from the office network to a home network using a VPN. A client is using a VPN and it disconnects and then reconnects. Even this establishes a new client ID. Note: This bug is scheduled to be resolved in 2025R1.

It can be installed on the client machine for single user deployments. A client must be able to connect to and stay connected to the license manager in order to open and use the software. The License Manager is managed via the License Management Center webpage.

Heartbeat
Every ~5min-10mins (hard coded and not adjustable), the client software checks-in with the server to ensure it keeps the license reserved. It's basically saying, I'm still here, don't give my license to anyone else. If the client can't reach the license server, it's considered disconnected and will retry every ~5-10min for up to 60min, displaying an error message every ~5-10min of this countdown. At the end of this countdown, the software will be placed into read-only mode.

idle timeout
The Idle Timeout feature, when enabled, will automatically check-in the licenses used by Ansys clients that are open by the user, but not actively being used by the user, so that these licenses can be made available to other users.

License Disconnect Timeout
The License Disconnect Timeout period is duration after which the License server is hard coded to automatically check-in licenses from clients that have been disconnected, so that they can be used by other users. This value is a hard-coded into the License Manager and varies by Ansys version.

License Feature
The term "license increment" and "license feature" are often interchanged, but there is technically a difference. A product license is made up of one or more license features (AKA license increments). A license feature is the actual license that gets checked out and is necessary to open the software and use specific features within that software.

License Increment
