2ExtendSim User Guide and Developer Reference

All ExtendSim products contain electronic files of the User Guide and Developer Reference. To access these manuals from within ExtendSim, give the command Help>ExtendSim Help. They can also be downloaded here.

The ExtendSim User Guide explains simulation concepts and has step-by-step tutorials that show you how to build, run, and analyze ExtendSim models. The tutorials are supported by example models and correspond to the different modeling technologies: continuous, discrete event, discrete rate, and 3D modeling.

The Developer Reference reveals the ExtendSim integrated development environment (IDE). It is a resource for modelers who use equation-based blocks as well as for programmers who create, modify, and debug ExtendSim blocks.

Support Plans

To make sure you're successful, technical support* is available either under an Annual Maintenance Plan or on a Per-Incident basis.


Maintenance PlanAnnual Maintenance Plan

Maintenance Plans cover basic usage questions and troubleshooting by our support staff as well as upgrades to major releases. In addition to support and upgrades, a Maintenance Plan offers the potential for first looks at upcoming products and features.

For concurrent-user (network) licenses of ExtendSim an annual Maintenance Plan for support and upgrades is required. For the first year, the Maintenance Plan is included in the price of the product; it must be renewed annually after the first year. Maintenance Plans cover basic usage questions and troubleshooting by our support staff as well as upgrades to major releases.

For single-user (stand alone) licenses of ExtendSim an annual Maintenance Plan for support and upgrades is optional but highly recommended. A Maintenance Plan subscription can only be purchased when a new single-user license or upgrade is purchased or within 60 days of that purchase.

Find complete details on Maintenance Plan features and benefits on Product Line.


Per-Incident SupportPer-Incident Support (available for single-user, stand alone licenses only)

If a Maintenance Plan is NOT purchased for a single-user license:


Our support staff will provide complimentary technical assistance for installation questions or bug reports related to the current release.

bullet Our support staff will provide complimentary assistance for basic usage questions and troubleshooting for a limited time. This support expires 60 days after the purchase of a new product or upgrade. (A Maintenance Plan may be purchased during this period.)
bullet For usage questions and troubleshooting after the first 60 days, purchase support on a Per-Incident basis; each incident is a discussion and resolution of one issue.

For questions on issues such as model building or debugging, writing or debugging custom code, or training in how to build a model or use ExtendSim, consulting and training services are available at additional cost through approved ExtendSim third party consultants and certified trainers.

Per-Incident Support can be purchased from our sales staff or through the ExtendSim Store. Consulting charges will be discussed with Support Personnel prior commencing the project.
