[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
The additional menu items for [Pre-processing Window] and the tree structure of [Object Browser] are explained in the following sections.
