[Pre-processing Window]

The functions of the [Pre-processing Window] are explained in this chapter.

The [Pre-processing Window] opens just after a new project is started. It is used to create input information that is necessary for the solver.

The Pre-processor handles the following operations:

• Importing geographic data
• Editing geographic data
• Creating grids
• Editing grids
• Setting calculation conditions
