ExtendSim CP 2026

ExtendSim CP 2026 provides a powerful environment for continuous process simulation, custom block development, and advanced model integration. It is ideal for modeling systems in which materials, fluids, energy, information, or other resources flow continuously through a process. ExtendSim CP also provides a flexible platform for creating custom simulation solutions, integrating external technologies, extending ExtendSim's capabilities, and developing reusable modeling components.

Whether you're analyzing chemical processes, water and wastewater treatment systems, ecological systems, control systems, sustainability initiatives, weather patterns, or other applications where time advances in equal intervals and values are recalculated at each simulation step, ExtendSim CP provides the tools needed to model, visualize, analyze, and optimize complex continuous processes.

In addition to its robust continuous modeling capabilities, ExtendSim CP 2026 includes the Python Bridge block for direct integration with Python code and libraries, along with enhanced diagnostics, improved reporting tools, and numerous performance and usability enhancements that help modelers work more efficiently and gain deeper insight into system behavior.

License Types

Subscription license

An ExtendSim Subscription license gives you continuous access to the latest release of ExtendSim — no upgrade costs, ever. An active Subscription includes:

• Access to all updates, patches, and compatibility fixes, plus upgrades to new major releases.
• Full technical assistance with installation, activation, troubleshooting, and basic usage questions.
• Predictable annual budgeting at a lower upfront cost for new licenses.
• Your work remains yours forever. If a Subscription is not renewed, ExtendSim will no longer launch; however, all models, blocks, and libraries you create remain your property and are not tied to the Subscription.

Renew anytime if a Subscription lapses.

Best for: Teams who want a low entry price and simple annual pricing for the latest features, updates, upgrades, and support.

Perpetual license + Maintenance & Support Plan (MSP)

A Perpetual license provides permanent lifetime ownership of whichever ExtendSim product and release you purchase. Coupling a Perpetual License with an annual MSP provides ongoing access to technical support, product updates, major upgrades, and other benefits that help you maximize your ExtendSim investment. The first year of the MSP is included with every new Perpetual ExtendSim CP license. Maintaining an active MSP provides for:

• Access to all updates, patches, and compatibility fixes, plus upgrades to new major releases.
• Full technical assistance with installation, activation, troubleshooting, and basic usage questions.
• After the first year, MSP must be renewed annually to remain active. If MSP lapses, you may continue using your licensed ExtendSim release indefinitely, but you will no longer receive updates, upgrades, or MSP benefits.

Best for: Organizations that prefer long-term software ownership and want to avoid an expiring license. Also ideal for customers upgrading existing ExtendSim licenses that are current on MSP.

License Options

Individual -- Choose an Individual license when ExtendSim will be used by a single user, or when multiple users each need dedicated, full-time access to ExtendSim. Purchase one license for each user's device. If you will be running an Individual license on a virtual machine or via RDP, contact the ExtendSim Team at Sales.ExtendSim@Andritz.com and provide the username so activation can be enabled.

Node-Locked -- Choose a Node-Locked license when ExtendSim will be installed on a single shared device. Multiple users can access and use ExtendSim on that device, but only one person can use it at a time. This option is ideal for computers in secure facilities, labs, or other controlled environments.

Note: Node-Locked licenses cannot be activated on virtual machines. For multiple users sharing a virtual machine, request a quote for a Floating license.

Floating -- A Floating license lets you install ExtendSim on as many machines as you need; the license server manages a pool of concurrent-use tokens, so any licensed user can check one out from any installed machine. This suits 3 or more people who use ExtendSim part-time, and also a single user who needs access from multiple machines (e.g. one for production work, one for development). Floating licenses are not available in the ExtendSim Store and must be ordered directly through Andritz Inc. or your ExtendSim Distributor.

CP Capabilities

ExtendSim CP 2026 provides advanced capabilities for building, analyzing, and optimizing continuous process systems, along with powerful development and integration tools for users who need more than traditional simulation software. It provides a flexible platform for creating custom simulation solutions, integrating external technologies, extending ExtendSim's capabilities, and developing reusable modeling components.

• Continuous Process modeling for systems involving for systems involving continuous flows of materials, energy, information, or other resources in business, scientific, and engineering applications.
• Rich process-oriented libraries containing blocks for control logic, process calculations, data management, reporting, visualization, and other common modeling requirements.
• Open-Source Libraries — All ExtendSim libraries are open source, giving users the freedom to access the underlying code and build their own custom blocks.
• Authoring environment for creating customized interactive user interfaces or control panels including animation.
• Integrated database technology that simplifies management of model inputs, operating parameters, historical data, and simulation results while supporting scalable model development.
• Python integration through the Python Bridge block, enabling direct access to Python libraries, advanced analytics, machine learning workflows, custom calculations, external data sources, and third-party services without leaving the ExtendSim environment.
• Enhanced diagnostics and notification center that centralizes status messages, warnings, errors, and model output in a persistent log for easier troubleshooting and model development.
• Data import, export, and connectivity tools for exchanging information with databases, spreadsheets, external applications, and other systems used throughout the enterprise.
• Advanced Reporting and Analysis Tools for collecting results, monitoring performance, conducting what-if analyses, and communicating simulation findings.
• Flexible, built-in IDE for creating custom components -- API, compiler, source code editor and debugger, dialog editor, graphical UI builder, include files, extensions, and more that allow organizations to create specialized modeling functionality when unique requirements arise.

System Requirements

Since simulation is processor-intensive, we recommend that your computer have a powerful central processing unit (CPU). The processor should be as fast as possible and it must be 64-bit.

For detailed specs, please see System Requirements on the ExtendSim web site.
