rough_log_law::rough_log_law_t Type Reference

Wall model based on the log-law for a rough wall. The formula defining the law is \( u^+ = log(z/z_0)/\kappa + B \). Here, \( z \) is the wall-normal distance, as per tradition in atmospheric sciences, where this law is often used. More...

Public Member Functions
procedure, pass(this)	init (this, scheme_name, coef, msk, facet, h_index, json)
	Constructor from JSON.
procedure, pass(this)	partial_init (this, coef, json)
	Partial constructor from JSON, meant to work as the first stage of initialization before the finalize call.
procedure, pass(this)	finalize (this, msk, facet)
	Finalize the construction using the mask and facet arrays of the bc.
procedure, pass(this)	init_from_components (this, scheme_name, coef, msk, facet, h_index, kappa, b, z0)
	Constructor from components.

	Compute the wall shear stress.
procedure, pass(this)	init_base (this, scheme_name, coef, msk, facet, index)
	Constructor for the wall_model_t (base) class.
procedure, pass(this)	partial_init_base (this, coef, json)
	Base type implementation of the deferred partial_init.
procedure, pass(this)	finalize_base (this, msk, facet)
	Base type implementation of the deferred finilize.
procedure, pass(this)	free_base (this)
	Destructor for the wall_model_t (base) class.
procedure, pass(this)	compute_mag_field (this)
	Compute the wall shear stress's magnitude.
procedure(wall_model_init), deferred, pass	init (this, scheme_name, coef, msk, facet, h_index, json)
	The common constructor.
procedure(wall_model_partial_init), deferred, pass	partial_init (this, coef, json)
	A part of the constructor that parses the JSON without initializing the base wall_model_t type. Used in wall_model_bc_t during the init stage of the bc construction. So, in this routine you cannot use the bc mask and facets. The construction can be finished by calling finalize_base. This generally follows the same pattern as in bc_t. This constructor gets the scheme_name from the JSON. This is currently hacked in by the pnpn_bc_factory.
procedure(wall_model_finalize), deferred, pass	finalize (this, msk, facet)
	Finalization of the partial construction, similar to bc_t.
procedure(wall_model_free), deferred, pass	free (this)
	Destructor.
procedure(wall_model_compute), deferred, pass	compute (this, t, tstep)
	Compute the wall shear stress.
procedure, pass(this)	find_points (this)
	Find the sampling points based on the value of h_index.
