Hi guys,<br><br>
I am trying to do a one-way nested run with ndown using wrfchemV3.3.1. I followed the procedure given in <a href="http://www.mmm.ucar.edu/wrf/OnLineTutorial/CASES/NestRuns/ndown1-2.htm" target="_blank">http://www.mmm.ucar.edu/wrf/OnLineTutorial/CASES/NestRuns/ndown1-2.htm</a>. I am facing problems on step 4 (Run ndown.exe). When i run ndown.exe it crashes in the very beginning but i don't get any error message. I ran ndown.exe with debug_level =100 and the output of rsl.out.0000 is as follows:<br><br>
NDOWN_EM V3.3.1 PREPROCESSOR<br>

After this line "Entering ext_gr2_joinit" ndown.exe crashes. I tried many things, like turned off the chemistry altogether, but nothing seems to work. I will be grateful if someone could could help in spotting where i am going wrong and how to fix it. Copied below is the namelist.input that i used for ndown.exe.<br><br><br>
