bht_boundaries_init

Build boundaries' meshes, compute the tangent and normal vectors, compute right hand side boundary terms of the NBVP.

Syntax

[discret_data,bound_data] = bht_boundaries_init(gene_data,discret_data,bound_data)

Description

The function is ran by bht_data_compile. 

It calls the M-Files in which the boundaries are described and computes:

• The coordinates of the discretization points (using the parameter mesh_size of the DAT-File).
• The coordinates of the tangent and normal vectors. 

Right hand side boundary terms arising in the NBVP (Neumann boundary value problem for the fluid potential) are also computed. 

Output variables

The structure array variables discret_data and bound_data are preallocated in the M-File bht_translation. The following fields are set up by bht_boundaries_init (we refer to the list of output variables for a description).

Field(s) of discret_data	Field(s) of bound_data
last_line	nbr_modes, nbr_points, t, dt, X, dl, Nn, N, K, flux, fflux
