We have created a software tool that can be used by scientists and engineers to create reduced order models (ROMs) of high fidelity simulations. We have invented mechanism that make this tool uniquely flexible. These inventions are:

-the ability to describe the input format of any simulator so that the format can be automatically processed by the ROM Builder
-a software framework that makes it possible to incorporate multiple sampling and regression algorithms, and to allow the user to choose options to creata a custom pipelien to generate a ROM
-automated methods for assessing the accuracy of the ROM and iteratively generating new samples to increase accuracy
