		MultiParticleContainer const *const	mypc )

◆ get_nuclear_fusion_type()

NuclearFusionType BinaryCollisionUtils::get_nuclear_fusion_type	(	const std::string &	collision_name,

◆ is_two_product_fusion_type() [1/2]

AMREX_GPU_HOST_DEVICE AMREX_INLINE bool BinaryCollisionUtils::is_two_product_fusion_type ( const CollisionType collision_type )

◆ is_two_product_fusion_type() [2/2]

AMREX_GPU_HOST_DEVICE AMREX_INLINE bool BinaryCollisionUtils::is_two_product_fusion_type ( const NuclearFusionType fusion_type )

◆ nuclear_fusion_type_to_collision_type()

◆ parse_scattering_processes()

amrex::Vector< ScatteringProcess > BinaryCollisionUtils::parse_scattering_processes ( const std::string & collision_name )

Parse the list of scattering processes of a dsmc or background_mcc collision and build the corresponding ScatteringProcess objects.

For each name in <collision_name>.scattering_processes, this reads the associated cross-section file (<process>_cross_section) and energy cost (<process>_energy). The energy is required for excitation and ionization processes, and optional (defaulting to 0) for all other processes.

Parameters

[in] collision_name the name of the collision

Returns: a vector of the parsed ScatteringProcess objects

◆ remove_weight_from_colliding_particle()

AMREX_GPU_HOST_DEVICE AMREX_INLINE void BinaryCollisionUtils::remove_weight_from_colliding_particle	(	amrex::ParticleReal &	weight,
		uint64_t &	idcpu,
		const amrex::ParticleReal	reaction_weight )

Subtract given weight from particle and set its ID to invalid if the weight reaches zero.
