bht_solids_data_init

Compute the solids' areas, centers of mass, momenta of inertia and the bodies' masses.

Syntax

[phys_data,bound_data] = bht_solids_data_init(gene_data,bound_data,phys_data)

Description

The function is ran by bht_data_compile. It calls the M-Files in which the fluid's boundaries are described and computes the areas and centers of mass of the solids. When necessary, it translates all of a boundary's discretization points (previously computed by the function bht_boundaries_init) in order to put the center of mass at the origin ; a warning message is next displayed in the current workspace.

The momenta of inertia and the masses of the solids are also computed and the mass matrix Ms is built. The total masses of the bodies are computed as well. 

The input variables gene_data, bound_data and phys_data are structure array variables which have been prealocated and partly set during the compilation by the functions bht_translation and bht_boundaries_init.

Output variables

The following fields are set up by bht_solid_data_init (see the List of output variables for a description).

Field(s) of phys_data	Field(s) of bound_data
Ms, solids_area, fishes_mass	X (if necessary)
