Function Documentation

bool box_inside_convex_polygon	(	const Particule &	S,
		const Bbox &	cell
	)

Check whether cell is fully contained in S.

Returns true if cell is fully contained in S and false otherwise.

Parameters

S	Particule
cell	Bbox

Warning: Specific coupling procedure !

Returns: bool

bool box_inside_tetra	(	const Tetrahedron &	tetra,
		const Bbox &	cell
	)

Check whether cell is fully contained in tetra.

Returns true if cell is fully contained in tetra and false otherwise.

Parameters

tetra	Tetrahedron
cell	Bbox

Warning: Specific coupling procedure !

Returns: bool

void Copy_f_m	(	Solide &	S1,
		Solide &	S2
	)

Copy values of fluid forces Ff and torques Mf from S2 to S1.

Function used in the semi-implicit scheme fixed-point procedure.

Parameters

S1	Solide at time t
S2	Solide at iteration k of the fixed-point procedure

Warning: Specific coupling procedure !

Returns: void

double Error	(	Solide &	S1,
		Solide &	S2
	)

Compute the error for the semi-implicit scheme.

The function is used as a stopping criterion in the semi-implicit scheme:

$\begin{eqnarray*} error = max( \, \Vert S1.solide[i].Dx - S2.solide[i].Dx \, \Vert_{\infty} + h_{max} \Vert \, S1.solide[i].e - S2.solide[i].e \, \Vert_{\infty})_i \end{eqnarray*}$

$\begin{eqnarray*} h_{max}=& max(abs(S1.max\_x - S1.min\_x),abs(S1.max\_y - S1.min\_y), \\ & abs(S1.max\_z - S1.min\_z), abs(S2.max\_x - S2.min\_x),\\ & abs(S2.max\_y - S2.min\_y),abs(S2.max\_z - S2.min\_z)). \end{eqnarray*}$

Parameters

S1	Solide at iteration k of the fixed-point procedure
S2	Solide at iteration k-1 of the fixed-point procedure

Warning: Specific coupling procedure !

Returns: double

bool inside_box	(	const Bbox &	cell,
		const Point_3 &	P
	)

Check whether point P is in the Bbox cell.

Returns true if P is inside cell and false otherwise.

Parameters

cell	Bbox
P	Point_3

Warning: Specific coupling procedure !

Returns: bool

bool inside_convex_polygon	(	const Particule &	S,
		const Point_3 &	P
	)

Check whether point P is inside the convex polygon S.

Returns true if P is inside S and false otherwise.

Parameters

S	Particule
P	Point_3

Warning: Specific coupling procedure !

Returns: bool

bool inside_tetra	(	const Tetrahedron &	tetra,
		const Point_3 &	P
	)
