Rugosity

Postby thiagotfn2@gmail.com » Mon Feb 28, 2011 15:42

Hi,

If I want to change the value of the rugosity in a especific place, I can put the value in a box? If yes, the DEFAULTVALUE remains outside the box?

Thanks,

Thiago.

Hi,

You can create a box file and define:

<begin_rugosity>
INITIALIZATION_METHOD : BOXES
DEFAULTVALUE : 0.0025
FILENAME : ..\\..\\GeneralData\\BoxesRugosity.dat
BOXES_VALUES : 0.0024 0.0023 0.0028
<end_rugosity>

This example works for 3 boxes. All grid cells that are outside the boxes are given the default value.

You can also do it with a grid data file (similar to a bathymetry file) and define:

<begin_rugosity>
INITIALIZATION_METHOD : ASCII_FILE
DEFAULTVALUE : 0.0025
FILENAME : ..\\..\\GeneralData\\Rugosity.dat
<end_rugosity>

Cheers,
Luis
