[RegCNET] Advection problem in WE direction

[Ajay Parottil]

Dear RegCM users,
                             I am using the RegCM 4.5 version for a
chemistry run for four years with one month of spin up time. Model ran
perfectly for 5 months and then simulation stopped with following error.

SL Advection problem in WE direction !
 Cannot compute DP at J =          144
                      I =           87
FATAL CALLED ---------------
  Fatal in file: mod_sladvection.F90 at line:      140
 SLADVECTION
When i checked the above file i got the reason for error as
if ( abs(xnp) >= 3 ) then
            write(stderr,*) 'SL Advection problem in WE direction !'
Kindly explain and help me in rectifying the error.
