Code:
while grep -q NaN Output3.out
do
    command
done

that's asking for an infinite loop though. usually put a limit on such things.

Code:
while grep ... && ((fail++ < 10)); do
    command ...
done

for example to kill loop. or maybe exit
Code:
while grep -q ...; do
  if ((fail++ > 100)); then
    echo "this really just isn't going to work. i give up" >&2
    exit 1
  fi
 
  command ...
done
