Ansys License Manager 2023 R1 — Practical Guide

Installation steps (concise)

1. Obtain license file and installer from Ansys (ensure you have admin credentials and entitlement).
2. On chosen server, install License Manager package for your OS.
3. Place the license file in the designated folder (e.g., C:\Ansys\Licensing\ or /opt/ansys/licensing/).
4. Start lmgrd and ansyslmd services; verify they run as system services.
5. Open required ports (configure firewall and network ACLs).
6. On client machines, set ANSYSLMD_LICENSE_FILE environment variable or enter server:port in Ansys licensing dialog.
7. Verify client checkout by launching an Ansys product and confirming license acquisition.

Troubleshooting checklist (practical)

• Client can't see server: ping server, telnet server port, verify DNS and firewall rules.
• "No feature" or "Feature not found": ensure license file has correct features and expiry date; check lmstat for feature availability.
• Port conflicts: ensure configured ports aren't used by other services; change port in license file and restart.
• Clock drift issues: verify NTP and correct time zone.
• Intermittent checkouts: inspect network stability, packet loss, and license server CPU/memory.
• License server crashes: collect logs, increase verbosity, contact Ansys support with logs and lmutil output.

Best practices

Use a dedicated, highly available license server (consider clustering or failover for critical teams).
Keep multiple copies of current and previous license files.
Restrict admin access and run services under a dedicated account.
Monitor usage with lmutil or License Manager Web UI to plan renewals and purchases.
Enforce time-limited test licenses on isolated networks.
Document rehost and renewal procedures and contact points.
