 **Implementation in FDS**
 
-FDS offers different modelling approaches, see section 7.2 in {cite}`FDS-UG-6.7.5`: DNS (Direction Numerical Simulation), LES (Large Eddy Simulation), VLES (Very Large Eddy Simulation), and SVLES (Simple Very Large Eddy Simulation — VLES with simplified physics). The default mode is VLES.
