Re: [pitlakq-users] Reservoir.txt file construction

[Dr. Mike Mueller]

You saved your reservoir.txt with a byte order mark (BOM). This adds some bytes
at the beginning of your file that cannot be seen. I changed this and the
preprocessing works for me. I attached a file that should work.

To prevent this, make sure you turn off the BOM when exporting from Excel
or other tools. Good editors, such as Notepad++ on Windows, allow you to remove
the BOM [1].

This is my output:

setting new values for path
setting new values for bathymetry
setting new values for bathymetry
preprocessing is running ...

total_volume n = 61.562878471959 Mio m3
total_volume entire lake= 61.562878471959 Mio m3
set bottom_elevation to: 1150.00
surface_area 930432.2743462626
runtime was 112.4 seconds

Looks like your lake is in the mountains. ;)
