In order to run Abaqus, a license needs to be checked out from a license server. Installing the license server and reading in the license file is not very complex in general. Difficulties can arise though, especially when the license server is on a different computer than the computer you want to run Abaqus on. We will discuss FLEXnet licensing here.

During a new installation of the Abaqus CAE software, the license server needs to be filled in, so Abaqus knows where to obtain a license. This implies the license server should already be installed and running. In fact, the installation will not continue normally without a reference to a working license server being filled in. If the license server is on the same pc, simply using ‘localhost’ is sufficient. For external license servers, either the computer name or ip-address can be used. A port number can be specified, if you wish to work with a non-default port. Otherwise, it is not necessary.
