Hello Ashaf. 

I did select the dust options.  The floating point exception occurred when the resolution was less than 45 km grid spacing -- no matter how small I made the time step.  (So errors at 30 and 40 km grid spacing).
Successful model run at DX = 45 or 50 km.  I used Grell cumulus with Kain-Fristch closure.
