Dear experts,

I met this SIGFPE error when running WRF4.5.1 on other HPC.
The error is shown below and attached:

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

Is this related to the NETCDF issue? Kindly take any suggestions to solve this issue.

There are a few issues in the namelist:
(1) please set dx = 4500, 1500, 500, and the same set for dy
(2) time_step = 10 is way too small for this case. Please try time_step = 27.
(3) if the model domain covers area with large topography, please increase the value of epssm from 0.1 to 0.5 or even larger
(4) You didn't set sst_update = 1, so please remove the lines below from your namelist:
auxinput4_inname = "wrflowinp_d<domain>"
auxinput4_interval = 180
io_form_auxinput4 = 2

Please change above options and try again.
