  Hello,
  When I tried to do the calculation for my project by fluent, it gave me a floating-point exception error. Can you tell me what does it mean and how to solve it?. please find the attached photo 1. Besides, it gave me this notice before calculation also as photo 2. Thanks in advance.

  The message means the solver is very unhappy about something and has had enough. The residuals also hint at there being problems. nLooking at the message, you're using an outflow boundary: don't. That's an old condition and won't work well with pressure boundaries, it's only in the code as we never take anything out and I last used it in the 90s.
