Hello everybody,

I have a namelist.wps with 3 domains as following:
parent_id = 1, 1, 2,
parent_grid_ratio = 1, 3, 3,
i_parent_start = 1, 91, 200,
j_parent_start = 1, 55, 110,
e_we = 301, 469, 547,
e_sn = 261, 358, 541,

map_proj = 'lambert',
ref_lat = 48.0,
ref_lon = -2.00,
truelat1 = 33.0,
truelat2 = 53.0,
stand_lon = -2.00,
while there is the message: "Successful completion of metgrid", There is a message of "Segmentation Error" in wrf.exe

NOTE: In ref_lon 15.0 and stand_lon 15.0 there is NO error. Everything is running properly.

Thanks in advance anyone who will spend his/her valuable time in examining this problem.
 
Hi,
Can you please attach your full namelist.input file used for running WRF, along with the full error log(s) (if you have several rsl.error.* files, please combine them into a single rsl.tar file to attach). Thanks!
 
Hi kwerner,
my name is Christos and thank you for your help.

Attached you can find the namelist.wps, the namelist.input and a Tar file with rsl.error.

Best Regards,
Christos

Christos,
Thanks for sending those. I can see several CFL errors in your rsl* files, which indicates that the model has become unstable. Take a look at this FAQ that discusses ways to tackle this problem.

Additionally, I would recommend trying to use more vertical levels - maybe 45-50. It's also possible that you're not using enough processors for the sizes of your domains. This FAQ discusses how to determine an appropriate number of processors.
