+The HVENT keyword specifies a vent which allows horizontal flow of gases through wall vents such as doors and windows.
 
-Vent which allows horizontal flow of gases through vents such as doors and windows. Compartment offsets are triplets from the compartment origin.  FACE is an integer from 1 to 4 counterclockwise from the origin defining which wall face to place the vent on when visualizing with Smokeview. It doesn't affect the dynamics of the calculation, just the way it looks. The size of the opening can be modified by EVENT. This changes the Opening\_Fraction from the initial value (set above) to some other value. Typical use is to start with the door open (Initial\_Opening\_Fraction~=~1) and use EVENT to close the door (Final\_Fraction~=~0).
