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...

	Constructor from JSON.

procedure, pass(this)	partial_init (this, coef, scheme_name, 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, bc_name, user)
	Finalize the construction using the mask and facet arrays of the bc.

	Constructor from components.

	Compute the wall shear stress.

procedure, pass(this)	extract_properties (this)
	Extract the values of rho at the boundary.

procedure, pass(this)	init_base (this, scheme_name, coef, msk, facet, sampler)
	Constructor for the wall_model_t (base) class.

procedure, pass(this)	partial_init_base (this, coef, scheme_name, json)
	Base type implementation of the deferred `partial_init`.

procedure, pass(this)	finalize_base (this, msk, facet, bc_name, user)
	Base type implementation of the deferred `finilize`.

procedure, pass(this)	free_base (this)
	Destructor for the wall_model_t (base) class.

	Compute the wall shear stress's magnitude.

procedure(wall_model_init), deferred, pass	init (this, scheme_name, coef, msk, facet, json)
	The common constructor.

procedure(wall_model_partial_init), deferred, pass	partial_init (this, coef, scheme_name, 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`.

procedure(wall_model_finalize), deferred, pass	finalize (this, msk, facet, bc_name, user)
	Finalization of the partial construction, similar to `bc_t`.

procedure(wall_model_free), deferred, pass	free (this)
