It is generally not a good idea to shut a laptop that's working hard. The
reason is many laptops direct hot exhaust air up the front of the screen,
and shutting the screen blocks the vent.
Obviously you should check the situation for your specific laptop, but I'd
recommend putting the laptop on a hard surface and leaving it open, which
will allow maximum airflow. Alternatively you can stand it on its end like
a book (assuming there are no vents on the sides that this would block).
As well as not overheating, better cooling may make your simulation run
faster because it can clock the CPU higher without overheating.
