Chapter 10: WinPHOTON

In Version 3.5.1, the Nu-PHOTON package was announced. Nu-PHOTON has now been renamed WinPHOTON, and has been made the default alternative post-processor in the VR-Editor/Viewer environment.

Features of WinPHOTON can be classified as:

• Interface features;
• Function features;
• Settings features.

Interface features include:

• Separate windows for entering information and for drawing. The program draws figures in the main window; but users enter commands and see program messages in a dialog window, namely the Command Console;
• WinPHOTON contains a standard menu interface and a set of dialog windows;
• Help and Tutorial use the Internet browser installed in the default operating system.

WinPHOTON has many function features not possessed by PHOTON including:

• the ability to allow users to: save, in a file, a drawn Figure as a set of commands;
• edit the USE-file while running the program;
• use any fonts installed in the operating system to create TEXT objects;
• change the order of object drawing;
• change the number of colours in the palette from 16 to 256 to draw CONTOUR objects and smooth images;
• edit parameters for almost all types of objects (GRID, TEXT, CONTOUR and others);
• delete any object from a list, (not only the last object as was the case in PHOTON);
• show boundaries of cut-cell control volumes if PARSOL is used for calculations;
• see results of calculations as graphical images and as tables of values for each field variable;
• create new macro-variables, assign values to them, use formulae for determination and apply them in a processing package;
• create a new field variable and use formulae for its determination or use calculated field variables and macro-variables. After creating new field variables, users can apply them to all methods of processing as for the usual variables calculated from PHI files;
• view the sequence of results for transient cases without editing the USE-file in animated mode and as a slide show.

WinPHOTON has new settings features for the user interface so that users can:

• set the colours of the background of drawing area, the default font, main lines and background of outside area;
• set the sequence of object drawing for various types: GRID, CONTOUR, TEXT etc.
