HYSPLIT Forum: hysplitbbs.arl.noaa.gov

i run dispersion test simulation with hysplit successfully,
but when i tried to run forward trajectory i get an error see below from the rsl.error :

forrtl: severe (174): SIGSEGV, segmentation fault occurred

from rsl.out log ,see below the messages when it stops:

ddd setup trajectories starting points!
tj= 1 56.85840 31.26782 0.9988247
ddd number of trajectories... 1
ddd kpt= 0 1 0.0000000E+00
ddd XPOS= 56.85840 31.26782 0.9988247 0

I attached the CONTROL,namelist.input and rsl.out.

So, please any one can help to solve the problem?
Thanks.

The rsl.out file was not attached.
The error message of "segmentation fault" is not helpful to diagnose what caused the termination of the run. Have you successfully run the simulation without turning on the trajectory?
The namelist file shows that you ran a WRF_CHEM core. The inline version of HYSPLIT is set up and tested with standard WRF_EM. All hysplit routines are in an extra directory (hysp/) included in the WRF model and do not interact (even know) other add-on packages like WRF_CHEM.

Hi,
Yes i can run Hysplit with traj turn off with both standard WRF-ARW or WRF-CHEM,
while always when i turn on traj i got segmentation fault even inline with standard WRF-ARW.

now i atahced rsl.out log file.
