Network License Restrictions
The Precipitation Module (TC-PRISMA) requires a separate license. If you are using a network client installation of Thermo‑Calc, then you may not be able to use it even if you have access to a license server with a valid network license file. The reason for this is because other clients who are part of your network installation may have checked out all instances of the network license allowed to run simultaneously.
For users with a network license, you must exit Thermo‑Calc to release the license for other users. The license is checked out as soon as you add a Precipitation Calculator and remains unavailable to other users until you exit the program.
With a network license, and if as per above you temporarily do not have access to a license, you are automatically put into Demo Mode. Then the Precipitation Calculator is available with three elements.
