Function Documentation

wall_free()

void wall_free

(

wall_data *

data

)

Free allocated resources.

Parameters

data	pointer to the data struct

Definition at line 29 of file wall.c.

wall_offload()

void wall_offload

(

wall_data *

data

)

Offload data to the accelerator.

Parameters

data	pointer to the data struct

Definition at line 46 of file wall.c.

wall_hit_wall()

int wall_hit_wall	(	real	r1,
		real	phi1,
		real	z1,
		real	r2,
		real	phi2,
		real	z2,
		wall_data *	w,
		real *	w_coll )

Check if a given directed line segment intersects the wall.

This function is intended to be used to check whether a marker collides with the wall. If there is a collision, this function returns an identification number specific to that wall tile. If the marker hits multiple wall elements, only the first one is returned.

This is a SIMD function.

Parameters

r1	start point R coordinate [m]
phi1	start point phi coordinate [rad]
z1	start point z coordinate [rad]
r2	end point R coordinate [m]
phi2	end point phi coordinate [rad]
z2	end point z coordinate [rad]
w	pointer to data struct on target
w_coll	pointer for storing the parameter in P = P1 + w_coll * (P2-P1), where P is the point where the collision occurred.

Returns

wall element id if hit, zero otherwise

Definition at line 80 of file wall.c.

wall_get_n_elements()

DECLARE_TARGET_END int wall_get_n_elements

(

wall_data *

w

)

Return the number of wall elements.

Parameters

w	pointer to wall data struct on target

Returns

Number of wall elements or zero on failure.

Definition at line 104 of file wall.c.

wall_get_flag()

DECLARE_TARGET_END int wall_get_flag	(	wall_data *	w,
		int	idx )

Return the flag of a wall element.

Parameters

w	pointer to wall data struct on target
idx	wall element index

Returns

Flag of the wall element.
