The ANSYS License Manager 2023 R1 is the backbone of the Ansys simulation ecosystem, providing the essential infrastructure to manage and deploy software seats across a network. Whether you are an individual engineer or a CAD manager at a global enterprise, understanding how to install, configure, and troubleshoot the 2023 R1 version is critical for maintaining an uninterrupted workflow.
This version introduces streamlined licensing workflows and improved stability for the latest 2023 R1 software suite, including flagship products like Fluent, Mechanical, and HFSS. Key Features and Improvements in 2023 R1
The 2023 R1 release focuses on administrative efficiency and enhanced communication between the client machine and the license server. Enhanced security protocols for FlexNet Publisher. Updated Ansys License Management Center web interface. Improved diagnostic logging for faster troubleshooting. Better support for cloud-based license borrowing. Seamless integration with Ansys Gateway powered by AWS. System Requirements for Installation
Before proceeding with the installation, ensure your server meets the following criteria to avoid service interruptions.
Supported OS: Windows 10/11 (64-bit), Windows Server 2019/2022, or supported Linux distributions (RHEL, CentOS, Ubuntu).
Hardware: Minimum 2GB RAM (8GB recommended) and at least 1GB of free disk space.
Network: A stable Ethernet connection with a static IP address or a consistent hostname.
Permissions: Full Administrative rights are required for installation and service management. Installation and Configuration Guide
Setting up the Ansys License Manager 2023 R1 involves three primary phases: installation, license file addition, and service activation. 1. Software Installation
Download the License Manager installer from the Ansys Customer Portal. Run the setup executable and follow the prompts. By default, the software installs to C:\Program Files\ANSYS Inc\Shared Files\Licensing. Once the installation is complete, the Ansys License Management Center will automatically open in your default web browser. 2. Gathering Server Information
To generate your license file, you will need your server's Hostname and FlexNet ID (often the MAC address). You can find these details directly in the License Management Center under the "Get System Hostid Information" tab. 3. Adding the License File
Once you receive your .lic file from Ansys, go to the License Management Center and click "Add a License File." Browse to your file and click "Install." The manager will automatically update the folder structure and prepare the file for the FlexNet service. 4. Starting the Service
Navigate to the "View Status/Start/Stop License Manager" section. Click "Start" to initialize the three main daemons: lmgrd.exe, ansyslmd.exe, and the administration service. A green checkmark indicates that the server is successfully broadcasting licenses to the network. Troubleshooting Common Issues
Even with a perfect installation, network or configuration hurdles can occur.
Firewall Blocks: Ensure that ports 1055 (FlexNet) and 1056 (Ansys Vendor Daemon) are open for inbound and outbound traffic.
Version Mismatch: The License Manager must be the same version or newer than the application software. A 2023 R1 License Manager can run 2022 R2 software, but a 2022 R2 Manager cannot run 2023 R1 software.
Hostname Resolution: If client machines cannot find the server, try using the server's IP address instead of the Hostname in the Ansys Client Licensing Settings.
Debug Logs: If the service fails to start, check the "View Discovery Log" or "View FlexNet Debug Log" in the Management Center for specific error codes like "Invalid Host" or "Port in Use." Best Practices for License Management
To ensure maximum uptime for your engineering team, consider these management strategies:
Regular Backups: Always keep a backup of your .lic files in a secure, off-server location.
Monitoring Usage: Use the "Display User/License Usage" tab to identify peak usage times and determine if your team needs additional seats.
Scheduled Updates: Align your License Manager updates with your IT department's maintenance windows to prevent sudden work stoppages. If you would like to move forward with your setup:
Download the installer package (from the Ansys Customer Portal) Locate your Host ID (via the License Management Center) Configure your network firewall (Ports 1055 and 1056)
Once installed, the central interface is the Ansys License Management Center (LMC). Access it via https://<server_hostname>:25721.
libnsl library.sudo dnf install libnslCause: The license server is not running or hostname resolution fails.
Solution:
lmstat -a -c 1055@localhost.ipconfig /flushdns.setup.exe (Windows) or the installation script (Linux).license.dat) from the Ansys Customer Portal. Ensure it contains SERVER lines for your hostname and MAC address.ANSYS.2023R1.LicenseManager.Windows.iso).ansysli_server.exe.https://localhost:25721.Symptoms: License remains checked out after borrowing period.
Root cause: Corrupt ansysli_borrow.dat on client.
Solution: Delete %APPDATA%\Ansys\v231\license\ansysli_borrow.dat (Windows) or ~/ansys/v231/license/ansysli_borrow.dat (Linux). Then run ansysli_client -borrow -return -feature <feature_name>.
During the installation wizard, you will be asked for server details:
