The UniSim licensing landscape: The “state of the union”
In the complex sectors of oil and gas, refining, and petrochemicals, Honeywell UniSim Design Suite is a foundational tool for steady-state and dynamic process modeling. However, managing its high-value entitlements through the proprietary UniSim License Manager requires more than basic oversight—it requires real-time intelligence.
The “steady-state” visibility gap
UniSim is often licensed via a hybrid model involving floating seats and tokens. A common challenge for engineering IT is the “simulation hang”: an engineer completes a complex heat-and-material balance but leaves the UniSim environment open while attending a project review or performing data reconciliation in other tools. This locks a high-value seat or a block of tokens. Without real-time UniSim usage analytics, you cannot distinguish between an active solver run and an idle background session.
The token-network contention
UniSim’s flexible licensing—supporting token-based, hybrid, and “commuter” (temporary locking) models—is designed for flexibility but can be a nightmare to audit. Without monitoring UniSim internal seat usage, organizations often find themselves over-paying for tokens to cover “peak” periods that are actually caused by poor license etiquette rather than genuine demand.
Quick summary: OpenLM for UniSim
OpenLM empowers process engineering firms to transform their simulation investment into a high-performance, data-driven operation.
- Unified simulation dashboard: Monitor UniSim Design alongside other industry standards like AspenTech, AVEVA, and KBC Petro-SIM.
- Identify “solver hoarding”: Detect when a UniSim session is open but the solver is inactive and no interactions are occurring.
- Token and hybrid support: Track the consumption of tokens and network seats to ensure you are utilizing the most cost-effective license type.
- Automated log and tool query: Native support for the UniSim NetworkLicenceManager tool and log file parsing via the OpenLM Broker.
- By-the-minute resolution: Gain high-fidelity insights into check-out and check-in events for precise project chargebacks.
Comprehensive solution framework
OpenLM provides a three-layered approach to help you manage UniSim licenses efficiently.
The visibility layer (global monitoring)
Gain a unified view of your floating UniSim pools. OpenLM interfaces with the UniSim License Manager to show current check-outs, user IDs, and machine names. This removes the “black box” of proprietary Honeywell licensing and shows you who is truly active in real time across global engineering hubs.
The automation layer (active management)
Move beyond manual seat audits. OpenLM’s active process monitoring identifies when the UniSimDesign.exe process is idle. By identifying these “zombie” sessions, you can encourage better license etiquette or manually release seats to ensure that critical, time-sensitive plant design reviews are never blocked.
The intelligence layer (strategic foresight)
Leverage advanced analytics to determine the true ROI of your process simulation stack. By analyzing UniSim usage frequency and token burn rates, you can justify every dollar spent and identify specific opportunities to consolidate licenses or shift to more cost-effective subscription tiers.
Technical details: The OpenLM UniSim integration
OpenLM uses a secure, Broker-based approach to capture high-fidelity data from your Honeywell environment, optimized for 2026 engineering standards.
Seamless connectivity and monitoring
- Native support: OpenLM natively supports the UniSim license manager type (configured via the OpenLM Broker).
- Broker-led precision: The OpenLM Broker (v4.14 or higher) is installed on the license server to query the NetworkLicenceManager tool and parse the UniSim logs locally.
- Standard port monitoring: OpenLM typically monitors UniSim over port 6607, but easily adapts to custom network configurations.
- Resolution: Captures usage events with by-the-minute resolution, providing a precise historical record for internal audits.
- Feature tracking: Monitor specific modules such as UniSim Dynamics, EO (Equation Oriented), and Safety System tools to ensure ROI on premium add-ons.
Advanced reporting
- Actual usage vs. assigned: Visualize the gap between your total license pool/tokens and your peak concurrent demand.
- Chargeback transparency: Automatically calculate and export billing data based on specific engineering projects or regional cost centers.
Strategic ROI and business value
Organizations leveraging OpenLM for UniSim typically see a 15–20% improvement in license availability.
- Procurement support: Use “verifiable usage” data to negotiate your next Honeywell renewal or token purchase based on actual demand.
- Increased engineering throughput: By identifying and reclaiming idle seats, you ensure your process engineers always have immediate access to the simulator.
- Compliance and governance: Maintain a continuous, verifiable record of usage to ensure you stay within your contractual limits and avoid unexpected true-up costs.
