Ethics COREHUBzero was specifically designed to help a scientific community share resources and work together with one another. But each hub is more than just a repository of information. It is a place where researchers and educators can share data and simulation tools online. Users can launch simulations and post-process results with an ordinary web browser--without having to download, compile, or install any code. The tools they access are not just web forms, but powerful graphical tools that support visualization and comparison of results.
