[RegCNET] SIGFPE: Floating-point exception

Dear colleagues:

We are trying to run RegCM with the following input namelist (below) and are getting the following SIGFPE: Floating-point exception - erroneous arithmetic operation. Screen shot is attached. Any idea what causes (and where) the SIGFPE? Any idea where the problem may be?

Thanks in advance,
