CFD images with a white background can sometimes be more aesthetically pleasing, or easier to include in presentations and reports, for instance when they are to be printed and distributed in a physical hard copy format. Pictures can easily be displayed in the graphics window with white background, or saved in a picture file format with a white background. The Workbench color scheme is always a blue color with a gradient. If you are working with the background color scheme, you can save picture files with a white background by selecting that option in File > Save Picture. If you prefer to do a screen capture of the graphics window and paste it into your presentation, use the Preview button in File > Save Picture to display the graphics with white background in a separate window. Be sure to choose the desired file type format, color specification and resolution before using the Preview button. If you prefer to work in the main graphics window with a white background, you can follow these instructions •Choose the Classic color scheme (GUI Display->Options) or (TUI /display/set/color/color-scheme) •Use TUI commands to set the desired background and foreground colors /display/set/color/background “white” and /display/set/color/foreground “black” •Use the TUI command /display/re-render to update the background and foreground colors in the graphics window
