D it became necessary to display the 3D data in 3D This 3D display can also be employed to visualize existing input model nodalizations in 3D Rather than patch an older 2D GUI to develop 3D displays a plan was formed to build a new RELAPS5 3D Graphical User Interface RGUI with 3D display as an integral part Because code users have had many ideas and concerns about the previous GUIs their input was sought for the form and capabilities of the new RGUI through various means including the RELAPS5 Newsletter questionnaire Larson 1995 electronic mail and direct feedback from numerous hands on demos such as at the 1998 RELAPS International Users Seminar Mesina 1998 Most of these were compiled in a functional requirements document Mesina 1996a and a summary can be found in Mesina 1996b The user input was combined with design input from RELAP5 3D developers and experts from both the GUI and ergonomics fields A partial list of capabilities follows e 3D display for thermal hydraulics neutronics and heat conduction e Easier method less user time and effort to generate masks for the 3D displays e Exploration of 3D display move viewpoint via zoom pan rotate and translate e Detailed view of data at volume or junction with just a mouse click on the screen e Interactive RELAPS run control start pause restart replay stop e On line documentation including Help buttons and balloons RELAP5 3D manuals etc e Easy access
