CMAQ v5.3.2 Running error

CMAQ Run Time Errors and Issues
1

Hi all. When I tried to run cctm in CMAQ-5.3.2, I got following error:

Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.

Backtrace for this error:
#0  0x2B3ACD5FC697
#1  0x2B3ACD5FCCDE
#2  0x2B3ACE08F3FF
#3  0x93A2F1 in m3dry_ at m3dry.F:652 (discriminator 4)
#4  0x6CAE36 in __depv_defn_MOD_get_depv at DEPV_DEFN.F:544
#5  0x91BE24 in vdiff_ at vdiffproc.F:411
#6  0x866510 in sciproc_ at sciproc.F:233
#7  0x854AE0 in cmaq_driver_ at driver.F:717
#8  0x84F4C7 in MAIN__ at cmaq_main.F:97

It’s strange that there are no obvious errors in the CTM_LOG.
Here I upload my script and logs, hope someone know the reason. Thanks!

Were you able to find a solution to this issue?

Your log.txt showed that the error was here:
Backtrace for this error:
#0 0x2B3ACD5FC697
#1 0x2B3ACD5FCCDE
#2 0x2B3ACE08F3FF
#3 0x93A2F1 in m3dry_ at m3dry.F:652 (discriminator 4)

#8 0x84F4C7 in MAIN__ at cmaq_main.F:97

Your CTM_LOG file had several warnings.

Several of these warnings:

ATTENTION: The Emissions Stream Label (WBDUST) applied for Rule   1
     in the Emissions Control Namelist does not match any of the emissions streams
     labels or families provided to CMAQ. Please check the
     runscript against your emissions control inputs
     confirm that this stream should be ignored.

Several of these warnings:
 *** ATTENTION **********************************************:
     The emission surrogate or member of family HONO
     was not found in the requested emission streams but the
     CTM_EMISCHK environment variable set to False so simulation
     will proceed.

I am also not familiar with running CMAQ using the Timestepping Parameters that you used.
#> Set Timestepping Parameters
set STTIME = 000000 #> beginning GMT time (HHMMSS)
set NSTEPS = 210000 #> time duration (HHMMSS) for this run
set TSTEP = 030000 #> output time step interval (HHMMSS)

Perhaps there is a miss-match between the variable names in the emissions control file and the variables available in your gridded emissions data files?

Another suggestion is to try to build and run the latest released version CMAQv5.3.3 to be sure that you have the latest bug fixes.
