Question
How do I install my license file?
Note
This document is exclusively intended for system administrators who need to install licenses on user and server machines. Before configuring license servers, you have to ask your local Siemens office for the corresponding license files. Depending on the type of license you want to install, the license management is different. Instructions for all situations are described below.
Answer
There are two types of license:
Floating licenses: A license server is used, and any client machines on the network can use Simcenter Amesim, up to the limit specified in the license file. A floating license must be set up on both the server and the client machines. The server and the client machine configurations are different.
Node-locked licenses: The license file is located on a stand-alone machine, and Simcenter Amesim can only be used on this machine.
Depending on the type of license you install and the type of machine you plan to configure, please refer to the relevant section in the list below.
