Hi there,
I've opened a thread, coming from here http://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=66&p=849#p849 because my problem seems to be more general.
I'm using WRF/WPS v4.0.1, intel compiler, mpi and netCDF-4 to do test simulations with large domains over Europe with ECMWF model data as input. I already used ECMWF data a lot in the past to drive WRF and I'm very confident that this has nothing to do with my input data.
Step 1: Set up a domain with 1000x1000 grid points
-> geogrid works
-> ungrib works
-> metgrid works
-> real works (with 80 levels and p_top_requested=5000)
-> wrf works and produced wrfout-files
Step 2: Set up a domain with 2000x2000 grid points. The only values which are changed in the namelist.wps are "e_we" and "e_sn". The ECMWF-grib data fully covers the extended domain.
-> geogrid works
-> ungrib works
-> metgrid works
-> real FAILS with "p_top_requested < grid%p_top possible"
I tried:
- changing the number of CPUs
- different location of the domain
- changing from ioform= 2 to ioform = 102 for metgrid, auxinput1, input and bdy (of course wit he same number of processors while running metgrid.exe/real.exe)
- switching to WRFV 3.9.1.1
but no with no success.
However, I found this post on the wrf-users mailing list, dating back to 2009, where a user raised this issue and this sound exactly like the problem I am facing right now
http://mailman.ucar.edu/pipermail/wrf-users/2009/001363.html
Does anybody have further information on that or managed to run real.exe on a huge large?
Any hints will be greatly appreciated!
