How to Check GT Suite Licenses with FlexLM

GT-SUITE is a software platform developed by Gamma Technologies for multiphysics modeling and simulation in the automotive, aerospace, and industrial sectors.

GT-SUITE is a software platform developed by Gamma Technologies for multiphysics modeling and simulation in the automotive, aerospace, and industrial sectors. It is used for thermofluid dynamics, acoustics, mechanics, and control analyses, providing an integrated environment for system-level simulation.

GT-SUITE license management is based on the FlexNet Publisher (FlexLM) system, which allows for the distribution of floating licenses. In this context, license monitoring is essential to ensuring efficiency, compliance, and continuous availability for distributed and rapidly evolving teams.

1. Configuring Monitoring Tools

The first step in properly monitoring GT-SUITE licenses is to configure the lmutil utility, provided by Flexera. This tool allows you to query license servers from the terminal, in both Windows and Linux environments.

Early Stages

Download lmutil: Make sure the version matches the one installed on the GT-SUITE license server.
Identify the port and server: GT-SUITE typically uses a vendor daemon called gtlicd. The port and hostname of the license server are specified in the License Manager configuration file or in the license file itself (e.g., port@server).

2. Check the available licenses

To find out how many licenses are available for GT-SUITE, you can use the following command:

lmutil lmstat -i -c porta@nomeserver

In the case of a high-availability configuration (triad), the command becomes:

lmutil lmstat -i -c porta@server1;porta@server2;porta@server3

or on Linux:

lmutil lmstat -i -c porta@server1,porta@server2,porta@server3

Sample Output


Feature           Version   #licenses  Expires        Vendor
gtsuite           2024      25         31-dec-2025    GTLICD

The results show that there are 25 GT-SUITE licenses available, valid through December 31, 2025.

3. Verify license usage

To find out who is using GT-SUITE at any given time, you can run:

lmutil lmstat -S gtsuite -c porta@nomeserver

Sample output:


Users of gtsuite:  (Total of 25 licenses issued; 10 licenses in use)
  "gtsuite" v2024, vendor: GTLICD
  floating license
    user1@DESIGN-PC1 (v2024) (SERVER/27000 1123), start Mon 07/15 08:45
    user2@TEST-PC3   (v2024) (SERVER/27000 1126), start Mon 07/15 09:05

4. Advanced Monitoring with Observer

Manually monitoring GT-SUITE licenses can become complex in distributed environments or with large teams. Observer allows you to fully automate FlexLM monitoring for GT-SUITE and other CAE software.

With Observer, you can:

Monitor GT-SUITE license usage in real time
Receive alerts for abnormal usage, capacity exhaustion, or expiration
Generate reports on usage peaks, trends, and KPIs
centrally manage licenses for various software and servers, including in a three-way configuration

Observer integrates directly with FlexLM and continuously collects usage data. This data is stored and displayed through interactive dashboards and periodic PDF/Excel reports, without the need for custom scripts or additional tools.

GT-SUITE is a strategic software solution for simulation and multidisciplinary design. Ensuring its availability, even in complex environments, is essential to the success of engineering projects.
