ModelRisk comes in three editions: Standard, Professional and Industrial. The Standard edition requires very little expertise in risk analysis, and reviewing some of the training videosa> should get you started. To make proper use of the Professional Edition, you should be a competent risk modeler or receive some training. The Industrial Edition is best suited for risk analysts with considerable experience.

The trial version is based on the Industrial Edition of ModelRisk, so it provides all the features you will find in the Standard, Professional and Industrial editions. Refer to this page for an overview of what each edition offers, or consult the help file for which editions contain a specific function or interface.

The trial version of ModelRisk has no constraints on model size, simulation speed, etc. However, the trial version has a delay built in that will require you to wait a few seconds before a simulation starts, and the graphs displaying the results have a watermark.

The student version is based on the Industrial Edition of ModelRisk, so it provides a complete set of features. The student version of ModelRisk has no constraints on model size, simulation speed, etc. However, the graphs displaying the results have a watermark.
