Hi, guys, I just ran the d

Hi, guys,

I just ran the damBreak4phaseFine case in the tutorials, while a floating point exception broke the program at the time 0.721885. Did anybody else encounter this also or have any ideas about how this happened?

Thank you very much.

The following is the message provided by the program.
