LS-DYNA

LS-DYNA is a finite element simulation tool developed by Livermore Software Technology Corporation (LSTC). LS-DYNA includes peripheral tools such as LS-OPT, LS_PREPOST, LS_TASC, and THUMS. Together they cover a wide range of physics simulation topics, from fluid dynamics to car safety.

LS-DYNA uses a proprietary license manager to control deployment of network licenses. With OpenLM, you can view license utilization, analyze usage statistics and patterns, and manage idle licenses.

OpenLM supports multiple license managers such as Flexera FLEXnet Publisher (FLEXlm) and Sentinel RMS. This document explains how to configure OpenLM to monitor LS-DYNA licenses.

Query the license server locally using OpenLM Broker and forward the information to OpenLM Server.

Before you begin

• OpenLM Platform
• OpenLM Broker v25.x or higher installed on the same machine as LS-DYNA, and approve it in Broker Hub.

Configure OpenLM Broker

How Broker interfaces with OpenLM Server.

Install and configure OpenLM Broker on the LS-DYNA license server machine. Broker queries the license server locally and forwards data to OpenLM Server. It also provides buffered communication to overcome network failures and security restrictions.

1. Open Broker UI at http://localhost:5090/.

2. Go to License Managers → Add License Manager.

3. In the Commands node, enter the full path to lstc_qrun.exe.

4. Click Apply.

5. Go to the Vendors node and enter the vendor name.

6. Click Restart Broker.

Approve LS-DYNA in OpenLM Platform

1. Sign in to OpenLM Platform.
2. From the menu, go to License Servers → Pending Server.
3. Select the LS-DYNA license manager, then select Approve and Merge.

Verify the integration

1. In OpenLM Platform, go to License Servers Live → Server Statistics.
2. Confirm LS-DYNA appears with a green status indicator.

note

It can take up to 3 minutes for the status to update for a new connection.
