[forrtl: severe (174): SIGSEGV, segmentation fault occurred] Running WRF v4.7.1

[Jisung Kim]

Hi everyone,

I have some problems with WRF.version 4.7.1,

There's something wrong with rrtmg_lw (or else).

Here's a snippet from 'rsl.error.0000'.

and attached namlist.input, namelist.wps.

Thanks for your help.

what's your input data source?

 

[William.Hatheway]

run these commands where your rsl output and error files are and see what comes up too

grep -i FATAL rsl.*

grep -i error rsl.*

grep -i SIGSEGV rsl.*

grep -i cfl rsl.*

 

[Jisung Kim]

what's your input data source?

LDAPS from KMA -> I made Vtable for this data.
also, GEOG 4.0 for geogrid
==================================

Only SIGSEGV has a result.
I've attached 'grep -i SIGSEGV > SIGSEGV.txt and also Vtable for LDAPS, grib2exe results for LDAPS grib2 file.

thanks

what's the native resolution of the ldaps system, like gfs is ~25x25km

 

[Jisung Kim]

1.5km x 1.5km

otherwise, the setting(what I had attached) in WRF v4.7.1 works in v4.6.0

 

[William.Hatheway]

few things i would try

1. run domain 1 by itself and see if it runs, then add each nest a repeat time to see if it can find the error that way
2.may something with metgrid soil levels i see 3 vs num_soil_levels = 4

i'm guessing but trying to help. ill have to wait for the admins to look as this is outside my scope
