Floationg point exception

      I've just create periodic zones and setup model but when I go to run for calculate ,the programe shows 'floating point exception'.

      However, when I didn't create periodic zones, the programe can calculate.

      Please recommend me for this case, what should I do.

      Hello, 

      How did you create your periodic zones?
