Description

Program Setup

- Default File Viewer

This option allows the user to change which program is used for viewing the report generator and logfile output. The default is the Windows Write program. The user can change this to any file viewer on their system.

- AVI Bin Directory

This option allows the user to set the default directory for where HEC-RAS will store bitmap files that it makes when creating an AVI movie file.

- Open last project

When this option is selected, the program will automatically open the last project worked on, during startup.

- Automatically backup data

When this option is checked, the program will automatically make a backup of the currently opened project, plan, geometry, and flow files. The backup files are updated at specific timed intervals, which is user controlled. The backup files are stored in the \HEC\RAS directory, with the titles RasBackup.prj, RasBackup.p01, RasBackup.g01, and RasBackup.f01.

- Set time for automatic backup

This option allows the user to control the time interval between updating the backup files. The default value is 20 minutes.

Default Parameters

This option allows the user to set defaults for some of the hydraulic variables.

Unit System

This option allows the user to set the default units system to either English or Metric. Once the units system is set, the program assumes that all input data are entered in that units system. Likewise, the display of all output data will be done in the default units system.

Convert Project Units

This option allows the user to convert an existing project from one units system to another. Projects can be converted from English to Metric or from Metric to English.
