Dear all, <br>I was running the model on the IBM P570 machine with 3 nested domains, 27, 9 and 3 kms. This problem I had reported earlier as well. The time step I have used is 120sec. The model was running up to 6hrs and after which It aborted by giving Core file. <br><br><br>I am attatching the namelist.input file and the rsl files. <br><br>bash-3.2$ ls -lrt wrfout* <br>-rw-r--r-- 1 51017984 Mar 08 03:06 wrfout_d01_2010-08-06_00:00:00<br>-rw-r--r-- 1 176907272 Mar 08 03:06 wrfout_d02_2010-08-06_00:00:00<br>-rw-r--r-- 1 252611432 Mar 08 03:06 wrfout_d03_2010-08-06_00:00:00<br>bash-3.2$ <br>bash-3.2$ ncdump -v Times wrfout_d01_2010-08-06_00:00:00<br>imes =<br> "2010-08-06_00:00:00",<br> "2010-08-06_01:00:00",<br> "2010-08-06_02:00:00",<br> "2010-08-06_03:00:00",<br> "2010-08-06_04:00:00",<br> "2010-08-06_05:00:00",<br> "2010-08-06_06:00:00" ;<br>}<br>bash-3.2$ <br><u><b>AS SUGGESTED, I have tried to look for NaN in the wrfout files but It does not exist.!!!!!!</b></u><br><br>bash-3.2$ ncdump wrfout_d01_2010-08-06_00:00:00 | grep -i NaN <br> IVGTYP:description = "DOMINANT VEGETATION CATEGORY" ;<br> ISLTYP:description = "DOMINANT SOIL CATEGORY" ;<br>bash-3.2$ ncdump wrfout_d02_2010-08-06_00:00:00 | grep -i NaN<br> IVGTYP:description = "DOMINANT VEGETATION CATEGORY" ;<br> ISLTYP:description = "DOMINANT SOIL CATEGORY" ;<br>bash-3.2$ ncdump wrfout_d03_2010-08-06_00:00:00 | grep -i NaN<br> IVGTYP:description = "DOMINANT VEGETATION CATEGORY" ;<br> ISLTYP:description = "DOMINANT SOIL CATEGORY" ;<br>bash-3.2$ <br>bash-3.2$ date<br>Tue Mar 8 03:29:15 IST 2011<br>bash-3.2$ <br><br>bash-3.2$ ls -lrt core*<br>coredir.5:<br>total 655848<br>-rw-r--r-- 1 335790224 Mar 08 03:07 core<br><br>coredir.3:<br>total 643664<br>-rw-r--r-- 1 329553200 Mar 08 03:07 core<br><br>coredir.2:<br>total 646352<br>-rw-r--r-- 1 330929600 Mar 08 03:07 core<br><br>coredir.1:<br>total 611240<br>-rw-r--r-- 1 312953392 Mar 08 03:07 core<br><br>coredir.7:<br>total 606376<br>-rw-r--r-- 1 310461104 Mar 08 03:07 core<br><br>coredir.6:<br>total 605224<br>-rw-r--r-- 1 309871168 Mar 07 05:15 core<br><br>coredir.4:<br>total 658528<br>-rw-r--r-- 1 337166176 Mar 08 03:07 core<br><br>coredir.0:<br>total 758952<br>-rw-r--r-- 1 388580736 Mar 08 03:07 core<br>bash-3.2$ ls -lrt core*<br><br>I have used GREP in the rsl files <br><!--[if gte mso 9]><xml>

Can you use ncview to look at your wrfout files? You may need to do
to those outputs that are right before model stopped. Please check
whether there is any weird data in those output files? <br>
<br>
Did you see any NaN when typing ncdump wrfout | grep -i Nan? <br>

Dear Sir, <br>
Thanks for the reply. I am running WRf 3.2 for the 3 domains 27, 9
and 3 km for the 48hrs Forecast on the IBM P570 Machine. The
Operating system is AIX5.3 and the code is compiled using xlf with
POE in place. <br>
I had given the command <b>bash$ time poe ../wrf.exe -procs 8. </b><br>
<br>
1. The model gave segmentation fault after 4hrs of Integration. I
also plotted the Model forecast for 2nd and 3rd hour at 27km
resolution (Domain 1) So it showed me some data being plotted <br>
<i> <b>But when I tried to plot the output for the 2nd and 3rd
domain, IT says ENTIRE GRID UNDEFINED. Kindly suggest. </b>
</i> <br>
<br>
2. >>>What data I have used ??<br>
<i><b>I am using the .grib2 files as Initial and BC taken from
<a class="ecxmoz-txt-link-freetext" href="ftp://ftpprd.ncep.noaa.gov.in" target="_blank">ftp://ftpprd.ncep.noaa.gov.in</a> at 1x1 degree resolution. </b><br>

3. >>>What is the error message in your output file? Did
you find any CFL violation? Your namelist.input looks fine.
Please send us error messages in your run.<br>
<b><i>I am attatching the rsl.error* and the rsl.out* files,

that there is no CFL violation. </b> <br>
