Detailed Description

Struct to store velocity properties, for use in momentum initialization.

Reads in and stores velocity used to initialize the Maxwellian and Maxwell-Juttner momentum distributions in InjectorMomentum. The information is read from the parameters of the species being initialized, and will be accessed by GetVelocity.

Constructor & Destructor Documentation

VelocityProperties()

VelocityProperties::VelocityProperties	(	const amrex::ParmParse &	pp,
		std::string const &	source_name )

Read runtime parameters to populate constant or spatially-varying velocity information.

Construct VelocityProperties based on the passed parameters. If velocity is a constant, store value. If a parser, make and store the parser function

Parameters

[in]	pp	Reference to the parameter parser object for the species being initialized
[in]	source_name	Optional group name of the input parameters

Construct VelocityProperties from the passed particle source parameters. Parse the momentum distribution type and initialize the corresponding velocity parameters: ux_mean, uy_mean, and uz_mean for maxwellian distributions, or bulk_vel_dir and beta for maxwell_juttner.
