NEAMS Workbench

The Nuclear Energy Advanced Modeling and Simulation (NEAMS) Workbench is a new initiative that will facilitate the transition from conventional tools to high-fidelity tools by providing a common user interface for model creation, review, execution, output review, and visualization for integrated codes. The Workbench can provide a common user input, including engineering-scale specifications that are expanded into code-specific input requirements through the use of customizable templates. The templating process enables multi-fidelity analysis of a system from a common set of input data.

To enable users to easily transition from one tool to another, an intuitive user interface is desired. Such an interface will provide guidance on the proper use of a tool by new or infrequent users without impeding the rapid generation or modification of inputs by experiences users. Visualization of input geometry and data files is desired, and the user interface should also provide easy access to computed results in text, tabular, and graphical forms. All integrated codes should be presented with a similar look and feel, and the comparison of results from multiple analyses should be available.
