ExtendSimExtendSim consists of a full range of tools for any type of simulation. No matter how you want to use ExtendSim - building models, running models, analysis, etc. - there is a package that will fit your needs.

There are ExtendSim products for building, experimenting with, and analyzing models - Model Developer Editions - and more specialized packages designed strictly for running models, analyzing models, or for use as a learning tool. Figure out which package might work best for you based on how you intend to use ExtendSim by visiting User Types.

The following products are for business users. Students and educators, go to Pricing for Universities.

Model Developer Editions

Create, use, and interactively run models, build custom interfaces and components, exchange data with and be controlled by other applications.

Each Model Developer Edition (MDE) of ExtendSim has the same core set of capabilities. In them you can create and build:

  • Models and interfaces, change values and settings, run simulations and animations, perform experiments, do analysis and optimization, save and export results.
  • Models to share with others to use in the Analysis RunTime, Player RunTime, Cloud, Student, and in other MDE versions of ExtendSim.
  • Custom blocks and libraries.

Model Developer products:

ExtendSim Model Developer Editions are available as Individual, Floating, and Node-Locked licenses.

30-day trials of the Model Developer Editions are available as a free download. Individual and Node-Locked licenses are available for purchase through the ExtendSim Store. Contact the ExtendSim Team at ANDRITZ Inc. or your local distributor to purchase Floating licenses.

   Specialized ExtendSim Products

These ExtendSim packages allow you to experiment with, optimize, and/or run analysis on models built in a Model Developer Edition (MDE).

Player RunTime

Player RunTime is a great way to view and explore ExtendSim models! Run the model with or without animation, watch as parameters and states change or items move, explore the model's settings and inner workings, and view simulation results. This free download allows you to open, run, watch, and explore models built in a Model Developer Edition of ExtendSim.

Analysis RunTimeAnalysis RunTime

ExtendSim Analysis RunTime is a cost-effective way to access the ExtendSim simulation engine without having to purchase a full Model Developer Edition of ExtendSim. Like the Player RunTime, you can run models and view results. Analysis RunTime adds the ability to change settings and parameters, perform optimization and scenario analysis, simulate for confidence intervals, save changes, and export the results to other applications for further analysis. Individual and Node-Locked ART licenses can be purchased and downloaded through the ExtendSim Store. For Floating licenses of ART, contact the ExtendSim Team or your local distributor.

ExtendSim CloudExtendSim Cloud

Companies use our self-hosted Cloud product to provide ExtendSim models in the cloud for use by their internal or external end-users. Cloud deployment allows the company's clients, such as its employees or customers, to have remote access to ExtendSim simulations without installing the ExtendSim application on their devices.

Once a company has set up the ExtendSim Cloud framework on a server, its clients submit credentials to get access to the ExtendSim models. Using a customized GUI front end (a web page in a browser or a standalone application) on their devices, the clients can send inputs through the cloud to the models, run the simulations, and receive the results on their computer, tablet, or smartphone.

A Cloud Services Manager coordinates all communication and data transfer between the client's front-end and ExtendSim; client access can be over a LAN or over the internet or other WAN. ExtendSim Cloud allows end users who have no simulation experience to benefit from the full power of ExtendSim. Click here for more information.

Maintenance and Support Plans (MSPs) are annual plans that are required for all ExtendSim products except Trial, Student, and Player RunTime.


The OEM license is for system builders who want to embed the simulation power of ExtendSim or ExtendSim technologies within their own applications. This license gives you the customized right to use and/or sell your product bundled with ExtendSim or ExtendSim technologies under your branded name.
