Detailed Description

Mesh based Monte Carlo source sampling.

Constructor & Destructor Documentation

Sampler() [1/3]

pyne::Sampler::Sampler	(	std::string	filename,
		std::string	src_tag_name,
		std::vector< double >	e_bounds,
		bool	uniform
	)

Constuctor for analog and uniform sampling

Parameters

filename	The path to the MOAB mesh (.h5m) file
src_tag_name	The name of the tag that describes the unbiased source density distribution.
e_bounds	The energy boundaries, note there are N + 1 energy bounds for N energy groups
uniform	If false, analog sampling is used. If true, uniform sampling is used.

Sampler() [2/3]

pyne::Sampler::Sampler	(	std::string	filename,
		std::string	src_tag_name,
		std::vector< double >	e_bounds,
		std::string	bias_tag_name
	)

Constuctor for analog and uniform sampling

Parameters

filename	The path to the MOAB mesh (.h5m) file
src_tag_name	The name of the tag with the unbiased source density distribution.
e_bounds	The energy boundaries, note there are N + 1 energy bounds for N energy groups
bias_tag_name	The name of the tag describing the biased source density distribution. The tag must have the same number of energy groups as <src_tag_name> or 1. If 1 (i.e. spatial biasing only), all energy groups within a mesh volume element are sampled equally.

Sampler() [3/3]

pyne::Sampler::Sampler	(	std::string	filename,
		std::map< std::string, std::string >	tag_names,
		std::vector< double >	e_bounds,
		int	mode
	)

Constuctor for overall sampler

Parameters

filename	The filename of the h5m file
tag_names	The map of src_tag_name and bias_tag_name
e_bounds	The energy boundaries, note there are N + 1 energy bounds for N energy groups
mode	The mode number, 0, 1, 2, 3, 4 or 5

Member Function Documentation

particle_birth()

pyne::SourceParticle pyne::Sampler::particle_birth

(

std::vector< double >

rands

)

Samples particle birth parameters

Parameters

rands

Six pseudo-random numbers in range [0, 1].

Returns

A SourceParticle object containing the x position, y, position, z, position, e, energy and w, weight of a particle.
