6. Requirements

The purpose of presenting these requirements is to inform the community about the present capabilities of the quoFEM app and features that could be added. The original set of requirements has come from a set of grand challenge reports, GC. These original requirements have been broken into a smaller set of deliverable features by the senior faculty associated with the project, SP. Additional requirements have come from users, U. See section Feature Requests if you have additional features you would like to see.
