- **Wind field**  ENVI-met includes a full 3D Computational Fluid Dynamics [[wp>Computational_fluid_dynamics|(CFD)]] modell. It solves the [[wp>Reynolds-averaged_Navier–Stokes_equations|Reynolds-averaged non-hydrostatic Navier-Stokes equations]] for each grid in space and for each time step. The effects of vegetation are included as drag forces in the wind field. For detailed building physics simulation, the wind flow close to each facade and roof segment is calculated. With the new Single Wall feature, wind patterns inside complex or semi-open structures can be simulated as well. + **Wind field**  ENVI-met includes a full 3D Computational Fluid Dynamics [[wp>Computational_fluid_dynamics|(CFD)]] model.

 The wind flow is updated at given time intervals. ENVI-met also supports a real-time flow calculation which means that the flow field is treated as a normal prognostic variable and calculated each step. Due to the very small time steps needed here, this way of calculation need very powerful computers.  The wind flow is updated at given time intervals.
