The ACT license is bundled with most Ansys 2024 R2 products. You must have a license to develop scripted extensions. You do not need to have a license to run binary extensions (WBEX files).
The ACT license enables two main capabilities:
Ability to load scripted extensions for development, debugging, and execution. When an ACT license is checked out, scripted extensions can be loaded. No matter how many scripted extensions are loaded, only one ACT license is checked out. This license is released once all scripted extensions are unloaded. If no ACT license is checked out, only binary extensions can be loaded.
Ability to build binary extensions from scripted extensions. The ACT license is checked out when a build starts and is released once the build finishes. If an ACT license is already checked out by a loaded scripted extension, the building of a binary extension does not require a second ACT license.
