The Ansys License Manager 2023 R1 serves as the critical backbone for managing simulation software entitlements, ensuring that engineering teams can access high-performance tools while administrators maintain security and efficiency. This version introduces significant architectural updates and streamlined management tools designed to handle increasingly complex multiphysics workflows. Core Functionality and the Management Center

At the heart of the 2023 R1 release is the Ansys License Management Center, a browser-based interface that centralizes all administrative tasks. This tool allows administrators to:

Monitor Real-Time Usage: View current license status and identify which users have checked out specific features.

Control Server Operations: Start, stop, or reread the license manager settings directly from the web interface.

Diagnostic Reporting: Generate detailed logs and FlexNet status reports to troubleshoot connectivity or entitlement issues. Key Technical Improvements

The 2023 R1 release incorporates updated backend components to improve security and performance:

FlexNet Publisher Update: The manager uses updated FlexNet client and server versions for more robust license handling. Summary

Multi-User Deployment: It is optimized for dedicated server environments, utilizing default ports 1055 and 2325.

Support for New Solvers: The 2023 R1 manager is essential for enabling the latest features in Ansys Fluent (such as the multi-GPU solver) and Ansys Mechanical (including AI-powered resource prediction). Flexible Licensing Options

To meet diverse engineering needs, Ansys continues to support multiple licensing models through this manager:

Concurrent Licensing: Traditional annual or perpetual licenses for frequent, consistent use.

Elastic Licensing: A pay-per-use model that allows teams to scale computing power and HPC capacity as needed.

Web-Based Roaming: Users can "check out" licenses for up to 30 days for offline use, removing the need for a constant internet connection while working remotely. Installation and Requirements

Setting up the 2023 R1 License Manager requires administrator access and specific hardware configurations:

OS Support: Windows 10/11 (Professional/Enterprise) or supported Linux x64 platforms. Key improvements in 2023 R1

Hardware: A minimum of 4GB RAM (8GB recommended for up to 400 concurrent users) and a stable 1Gbps Ethernet connection.

Firewall Configuration: For network access, administrators must configure the Windows Defender Firewall to allow traffic through the designated Ansys ports and application executables like lmgrd and ansyslmd.

The 2023 R1 release represents a shift toward more flexible, high-performance simulation management, ensuring that as engineering demands grow, the underlying licensing infrastructure remains secure and scalable.

Cause: Borrowing is not enabled by default in R1 releases.
Solution: Add to ansyslmd.opt: BORROW 720 (borrow time in hours). Clients must set environment variable ANSYSLMD_BORROW=1.

Cause: Port conflict. Another service uses port 1056.
Solution: Force a different port by editing license.dat:

VENDOR ansyslmd port=2080

Then restart the license manager.

With cyber threats targeting engineering IP, securing the 2023R1 license manager is non-negotiable.

  • Update the License Manager: While 2023R1 has no more feature updates, apply any critical security patches from Ansys support.

    • | File | Purpose | |------|---------| | license.dat | Your ANSIS-supplied license file (must be placed in licenses/ folder) | | lmgrd | Starts/stops the license server | | ansysli_server | ANSYS-specific license server wrapper | | lmstat | Check available licenses and users | | lmutil lmhostid | Get MAC address for generating license file |

    Cause: Firewall blocking port 1056 (ansyslmd vendor daemon).
    Solution: Add inbound rules for ports 1055, 1056, and 25721. On Linux, check iptables or firewalld.
