International Settings

Written by ironcore | June 10, 2014

To my international HEC-RAS user friends.  It’s time again to remind everyone that you need to have your Region and Language Windows settings set to English (United States), particularly if you are running unsteady HEC-RAS models.  If you live somewhere other than the USA, and you get an error message relating to the “time” data, or “date” inputs, it’s a good bet that you need to change your region and language settings.

    Thank's Chris… I've always thought that setting any English format was enough… I've always set English (Australia), because it's the fisrt of the English format list, and HEC-RAS computed ok…
    But once I got an error message abou time, and now I know why!!!!
    Best regards.

    After i change the format as seen above, the plan file does not read the date right and the date column is empty…

    Try re-entering the dates in the unsteady flow analysis window in this format: 04JAN2018
