Initial Dialog Boxes

When the user first starts GoPhast, the Start-Up dialog box is displayed.  If the user chooses to create a new model in the Start-Up dialog box, the Initial Grid dialog box is displayed.  After both these dialog boxes are closed, the main window of GoPhast is displayed (p. 12).

Start-Up Dialog Box

The Start-Up dialog box is displayed when first starting GoPhast.  It prompts the user either to start a new project or to open an existing GoPhast project.  The five most recently opened files will be listed among the choices.  If the user chooses to start a new project the Initial Grid dialog box will be displayed.

Initial Grid Dialog Box

The Initial Grid dialog box is used to specify the grid when starting a new GoPhast project either when first starting GoPhast or by selecting File|New.  In it, the user specifies the dimensions of the grid (the number of columns, row, and layers of nodes) and the spacing between nodes in the column, row, and layer directions.  The user must also specify the X, Y, and Z coordinates of the grid origin.  The grid origin is the location of the node in the first column, row, and layer.  Columns are numbered from left to right.  Rows are numbered from front to back. Layers are numbered from bottom to top.  Thus the grid origin is the node at the left, front, bottom, corner of the grid.  The grid angle must also be specified.  The angle is measured in degrees counterclockwise from the X-axis.  The vertical exaggeration must also be specified.

Clicking the Finish button will create a grid with the dimensions and location specified.  If the Do not create initial grid button is clicked instead, a new project will be created without a grid.
