ANSYS License Guidelines to Provide Access from Nimbix


First, you will need to open the ports below in order to allow access for the Nimbix ANSYS applications to reach your license server and check out licenses. These ports will need to be open through the VPN (if applicable) and through the actual machine that the license manager is hosted on. You only use these standard ANSYS ports below, we cannot change them. If you do not use standard ANSYS ports, you will have to set up port forwarding if using a VPN.

  1. Allow ports:
  • 1055
  • 2325
  • 2326
  1. Add the appropriate ports to the license file

Next, the person that manages the license server will need to edit the actual license file so that we can take advantage of these ports. You’ll need to add “1055” to the very end of the “SERVER” line and “port=2326” to the end of the “VENDOR” line. It should look like below: (only add the lines in RED - do not change the other variables in either of these lines. If you do, then the license won’t work)


SERVER <hostname> <hostid> 1055
VENDOR ansyslmd port=2326



  1.       Add user ‘nimbix’ to your options file

 If you have an options file for your users, you’ll need to add user “nimbix” to that options file. All users on that use Nimbix to start a job will come across as user ‘nimbix’. This is something that cannot be changed, so user “nimbix” will need to be added in order for the license server to allow users to check out licenses.


  1.       Add ansyslmd.ini if you are using an external IP address

 If you are hosting the license file and we are connecting to it through the internet through an external IP, you’ll need to have a file named ansyslmd.ini so that the license manager knows what it’s external IP is. The contents of the file will just be 1 line.

  • Create a file named ‘ansyslmd.ini’ in the .../licensing/ directory
  • On Linux the ansyslmd.ini contents should just include 1 line:
  • On Windows the ansyslmd.ini contents should just include 2 lines:
    • SERVER=1055@<hostname>
    • ANSYSLI_SERVERS=2325@<hostname>


  1. Add 2 host entries to hosts file 
  • Run "Notepad" as Adminstrator
  • From Notepad, open this file: c:\Windows\System32\Drivers\etc\hosts
  • Add the license server IP and hostname of the license server to this file
  • Add the license server IP and FQDN (<hostname> of the license server to this file
  • File > Save to save the changes


In order for the changes in the license file to take effect, you’ll need to restart the license server.
