Re: [Anuga-user] acos error

[Stephen R. <ste...@an...>]

Hi Karin,


I don't think we need that warning message (at least not so many messages).


So I have disabled the warning message in the most recent version of anuga on github. Let me know if you run into a problem after you have updated.


By the way, the finalise() command should be right at the end of your script.


Cheers

Steve

Subject: [Anuga-user] acos error

Hi all,

My most recent anuga models seem to be having some rounding errors in
the finalize() step in line 182. It goes through all the timesteps,
merges the sww files, and then prints a lot of lines that say "NOTE:
changing argument to acos from 1.00000000000222 to 1.0" after each
calculation for stage, elevation, xmomentum, and ymomentum for each
timestep before writing the gauge output csv file. The output files
all seem fine, but it significantly increases (doubles) the model
runtime. I'm attaching my hydrograph-generating script (txt2tms.py)
and the model script (flood_simn065_LGC3_drum_full_parallel_cpts.py).
I started encountering this error after using the
hydrograph-generating script to set my parameters instead of having
one constant discharge for the full run, so perhaps that has something
to do with it? If anyone has any suggestions on how to fix this error
it would be greatly appreciated!

Thanks,
Karin Lehnigk
