Function Documentation

void scharge_add_from_trajectory_pic	(	MeshScalarField &	scharge,
		pthread_mutex_t *	mutex,
		double	I,
		const ParticleP2D &	x1,
		const ParticleP2D &	x2
	)

Function for adding charge to space charge density map from particle trajectory in 2d simulation.

Adds contribution to space charge density map scharge from a particle carrying current per length I travelling from x1 to x2. Charge density is added to the mesh assuming that it is localized at the point where particle was at time 0.5*(t1+t2). This function is supposed to be used so that x1 and x2 are at the mesh intersection points, through which particle trajectory has passed.

void scharge_add_from_trajectory_pic	(	MeshScalarField &	scharge,
		pthread_mutex_t *	mutex,
		double	I,
		const ParticlePCyl &	x1,
		const ParticlePCyl &	x2
	)

Function for adding charge to space charge density map from particle trajectory in cylindrically symmetric simulation.

Same as for scharge_add_from_trajectory(). Now I is real current (A).

void scharge_add_from_trajectory_pic	(	MeshScalarField &	scharge,
		pthread_mutex_t *	mutex,
		double	I,
		const ParticleP3D &	x1,
		const ParticleP3D &	x2
	)

Function for adding charge to space charge density map from particle trajectory in 3d simulation.

Same as for scharge_add_from_trajectory(). Now I is real current (A).

void scharge_finalize_pic

(

MeshScalarField &

scharge

)

Finalize space charge calculation.

Converts charge map built by calls to scharge_add_from_trajectory() to space charge density map suitable for potential solvers. Also corrects boundary space charge values.
