With v12.0, all floating network licenses of FEMAP and FEMAP w/NX Nastran automatically include the option to borrow a license for up to 30 days. To borrow, you must be connected to your network, and able to communcate with the machine hosting your FEMAP FLEXlm license. There is a program called BORROW.EXE in the main FEMAP directory (we don't create a link to it, but probably should in the future).
Run BORROW.EXE, and enter the the name of your FEMAP License Server preceded by the "@" character, you will see something like this -
Choose the the features that you wish to borrow. If you are also borrowing NX Nastran features, please make sure you choose all that you will need when you disconnect from the network.
Set the number of days you wish to borrow for. The features that you borrow will stop working at the end of this time limit on your machine, and will automatically be returned to the pool, even if you are not connected to the network.
Press the "Borrow Selected" button and the licenses will be transferred to your machine.
You can now disconnect from the network, and continue to work with FEMAP and NX Nastran.
If you reconnect before the borrow expiration date, you can return the licenses early using the same BORROW.EXE utility.
