Function Documentation

guint gfs_cut_cube_vertices	(	FttCell *	cell,
		gint	maxlevel,
		FttVector *	p,
		FttVector *	n,
		FttVector	v[12],
		FttDirection	d[12],
		GfsVariable *	var,
		gdouble	val[12]
	)

Parameters:

cell	a #FttCell.
maxlevel	the maximum level to consider (or -1).
p	a point on the plane.
n	the normal to the plane.
v	where to return the vertices coordinates.
d	where to return the direction.
var	a #GfsVariable or NULL.
val	where to return the values of var or NULL.

Fills v, d and val with the coordinates/values of the vertices, intersections of cell with the plane defined by p and n.

The vertices are ordered consistently to define a consistent, oriented polygon.

Returns:

the number of vertices (0 if the plane does not cut the cell).

Here is the caller graph for this function:

void gfs_draw_boundary_conditions	(	GfsDomain *	domain,
		FILE *	fp
	)

Parameters:

domain	a fluid domain.
fp	a file pointer.

Outputs in fp an OOGL (geomview) representation of the boundary conditions of the domain.

void gfs_draw_refined_boundaries	(	GfsDomain *	domain,
		FILE *	fp
	)

Parameters:

domain	a fluid domain.
fp	a file pointer.

Outputs in fp an OOGL (geomview) representation of the boundaries of the refined domains.

Here is the call graph for this function:

void gfs_draw_solid_boundaries	(	GfsDomain *	domain,
		FILE *	fp
	)

Parameters:

domain	a fluid domain.
fp	a file pointer.

Outputs in fp an OOGL (geomview) representation of the solid boundaries of the domain.

Here is the call graph for this function:

gboolean gfs_plane_cuts_cell	(	FttVector	plane[3],
		FttCell *	cell
	)

Parameters:

plane	three points belonging to the plane.
cell	a #FttCell.

Returns:

TRUE if plane cuts cell, FALSE otherwise.
