File Menu
New
New deletes the current CSG model and creates a new, empty model called "Untitled."
Open . . .
Open . . . displays a dialog box with a list of existing M-files from which you can select the file that you want to load. You can list the contents of a different directory by changing the path in the Selection text box. You can use the scrollbar to display more filenames. You can select a file by double-clicking the filename or by clicking the filename and then clicking the Done button. When you select a file, the CSG model that is stored in the model M-file is loaded into the PDE Toolbox and displayed. Also, the equation, the boundary conditions, and information about the mesh and the solution are loaded if present, and the modeling and solution process continues to the same status as when you saved the file.
Save As . . .
Save As . . . displays a dialog box in which you can specify the name of the file in which to save the CSG model and other information regarding the GUI session. You can also change the directory in which it is saved. If the filename is given without a .m extension, .m is appended automatically.
The GUI session is stored in a model M-file, which contains a sequence of drawing commands and commands to recreate the modeling environment (axes scaling, grid, etc.). If you have already defined boundary conditions, PDE coefficients, created a triangular mesh, and solved the PDE, further commands to recreate the modeling and solution of the PDE problem are also included in the model M-file. The pdetool GUI can be started from the command line by entering the name of a model M-file. The model in the file is then directly loaded into the GUI.
Print . . .
Print . . . displays a dialog box for printing a hardcopy of the PDE Toolbox figure. Only the main part of the figure is printed, not the upper and lower menu and information parts. In the dialog box, you can enter any device option that is available for the MATLAB print command. The default device option is -dps (PostScript for black and white printers). The paper orientation can be set to portrait, landscape, or tall, and you can print to a printer or to file.
