Dear all,
Has any of you experienced this error?, I just (re)downloaded anuga and
tried to run the channel3_parallel.py file under the instruction

mpiexec.openmpi -np 4 python channel3_parallel.py

and it runs perfectly until it reaches the instruction

domain.sww_merge(verbose=True)

The traceback of the error is

Traceback (most recent call last):
File "test_par.py", line 95, in <module>
domain.sww_merge(verbose=True)
File
"/home/jose/anuga_core/source/anuga_parallel/parallel_shallow_water.py",
line 168, in sww_merge
merge.sww_merge_parallel(global_name,self.numproc,verbose,delete_old)
File "/home/jose/anuga_core/source/anuga/utilities/sww_merge.py", line
40, in sww_merge_parallel
_sww_merge_parallel_smooth(swwfiles, output, verbose, delete_old)
File "/home/jose/anuga_core/source/anuga/utilities/sww_merge.py", line
386, in _sww_merge_parallel_smooth
g_points[node_l2g,0] = fid.variables['x']
IOError: Index exceeds dimension bound


I tried to write some 'prints' in the sww_merge.py but everything seems to
be fine.

Thank you all,

Jose

Hi Jose,

Running channel3_parallel should have produced some sww files with names
channel3_P4_0.sww, channel3_P4_1.sww, channel3_P4_2.sww, channel3_P4_3.sww,

It would be interesting to see if you get the same error running
sww_merge from the command line

run

python /home/jose/anuga_core/source/anuga/utilities/sww_merge -f
channel3 -np 4 -v

and see if you get the same error.

Can you also do an ls -l to see the sizes of the channel3_P4_*.sww files.

Using ls -l channel3*.sww I get

steve@bottineau:~/anuga/anuga_core/demos$ ls -l channel3*.sww
-rw-rw-r-- 1 steve steve 59824148 Dec 4 07:10 channel3_P4_0.sww
-rw-rw-r-- 1 steve steve 58872820 Dec 4 07:10 channel3_P4_1.sww
-rw-rw-r-- 1 steve steve 59698892 Dec 4 07:10 channel3_P4_2.sww
-rw-rw-r-- 1 steve steve 60325124 Dec 4 07:10 channel3_P4_3.sww
-rw-rw-r-- 1 steve steve 234961428 Dec 4 07:10 channel3.sww


What version of netcdf are you using? I might need to change the line
where the error occurred from

g_points[node_l2g,0] = fid.variables['x']
to
g_points[node_l2g,0] = fid.variables['x'][:]

to cover your version of netcdf.

Cheers
Steve
