Data Types
type	les_model::les_model_t
	Base abstract type for LES models based on the Boussinesq approximation. More...
interface	les_model::les_model_compute
	Compute eddy viscosity. More...
interface	les_model::les_model_init
	Common constructor. More...
interface	les_model::les_model_free
	Destructor. More...
interface	les_model::les_model_allocate
	LES model allocator. More...
type	les_model::allocator_entry

Modules
module	les_model
	Implements les_model_t.

Functions/Subroutines
subroutine	les_model::les_model_init_base (this, fluid, nut_name, delta_type, if_ext)
	Constructor for the les_model_t (base) class.
subroutine	les_model::les_model_free_base (this)
	Destructor for the les_model_t (base) class.
subroutine	les_model::les_model_compute_delta (this)
	Compute the LES lengthscale. For each GLL point, we take the distance between its neighbours in all 3 directions divided by 2 with the exception of face nodes, where only one neighbour exists. To form the lengthscale the distances along 3 directions are multiplied, and a cubic root is extracted from the result. This roughly corresponds to a cubic root of the cell volume in FVM computations.

Variables
character(len=20), dimension(3)	les_model::delta_known_types = [character(len=20) :: "pointwise", "elementwise_average", "elementwise_max"]
type(allocator_entry), dimension(:), allocatable	les_model::les_model_registry
	Registry of LES model allocators for user-defined types.
integer	les_model::les_model_registry_size = 0
	The size of the les_model_registry
