Detailed Description

template<int dim, typename number>
struct MeltPoolDG::CompressibleFlow::InputDefinedInitialCondition< dim, number >

Struct for storing initial condition information and creating a corresponding function object for use in simulations. This can be used to provide cases where via the input file the user can specify the initial condition of the simulation, e.g., by providing functions for the initial density, velocity, and energy fields. For multi-component flow cases, the user can also provide functions for the initial species mass fraction fields.

Member Function Documentation

add_parameters()

template<int dim, typename number >

void MeltPoolDG::CompressibleFlow::InputDefinedInitialCondition< dim, number >::add_parameters

(

dealii::ParameterHandler &

prm

)

Adds all required parameters for the initial condition to the parameter handler.

Parameters

prm	Parameter handler to which the parameters will be added.

create_initial_condition_function()

template<int dim, typename number >

std::shared_ptr< dealii::Function< dim, number > > MeltPoolDG::CompressibleFlow::InputDefinedInitialCondition< dim, number >::create_initial_condition_function	(	const number	initial_time,
		const int	n_species = 1
	)		const

Creates a function object representing the initial condition based on the data stored in this struct.

For multi-component flow cases, this returns a ConservativeVariablesFunction initialized with the provided strings for density, velocity, energy, and species mass fractions. For single-species flow cases, the returned function is initialized with density, velocity, and energy only; species mass fractions are ignored.

Parameters

initial_time	Initial time used to initialize the function.
n_species	Total number of species in the simulation. Determines how many species mass fraction functions are initialized in the returned function. Set to 1 for single-species cases.
