open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi All.
I want to explain my problem.
In my project,i don't want insert a "classic" bottom friction law,but i want to use the non-submerged vegetation friction,dividing the bed river in two part with different characteristics of "diameter" and "density".
In order to make this,in fudaa-preprocessor editor...

law of bottom friction = 0
non-submerged vegetation friction = v
friction data = v
friction data file = frictionlaw.txt
formatted data file = fr.txt

...is it right???How do i have to structure the file "frictionlaw.txt" in this case???

Best reguards.

Hi
You have an example of such data files in the test case named DONAU
You could also find some informations in the user manual of Telemac-2D

Thanks.
The problem is in a table in telemac2d user manual because there is the keyword NFRO,but the right one in NOFR.

Reguards.
