Detailed Description

Atmospheric Boundary Layer physics

This class implements the necessary code to simulation atmospheric boundary layers with AMR-Wind. It reads the namespace ABL from the input file to determine how the initial conditions are generated. At each timestep it performs plane averages to collect statistics as well as set the necessary data to be used by wall models as well as any ABLForcing terms that might be active.

Initialize the velocity and temperature fields at the beginning of the simulation.

post_advance_work()

void amr_wind::ABL::post_advance_work ( )

override

Perform tasks at the end of a new timestep

For ABL simulations, this method writes all plane-averaged profiles and integrated statistics to output

override

pre_advance_work()

void amr_wind::ABL::pre_advance_work ( )

override

Perform tasks at the beginning of a new timestep

For ABL simulations this method invokes the FieldPlaneAveraging class to compute spatial averages at all z-levels on the coarsest mesh (level 0).

The spatially averaged velocity is used to determine the current mean velocity at the forcing height (if driving pressure gradient term is active) and also determines the average friction velocity for use in the ABL wall function computation.
