Member Function Documentation

point_inside_jet_hole()

template<int dim, typename number >

bool MeltPoolDG::CompressibleFlow::FreeJetInflow< dim, number >::point_inside_jet_hole ( const dealii::Point< dim, number > &  location ) const

private

Checks whether a given point is located within the circular area (the "jet hole") where the free jet inflow is applied.

Parameters

location

The spatial location to check.

Returns

True if the point is inside the jet hole, false otherwise.

set_time()

template<int dim, typename number >

void MeltPoolDG::CompressibleFlow::FreeJetInflow< dim, number >::set_time ( const number  new_time )

override

Sets the current time for the function.

Parameters

new_time

Time to be set.

set_velocity_ramp_up()

template<int dim, typename number >

void MeltPoolDG::CompressibleFlow::FreeJetInflow< dim, number >::set_velocity_ramp_up	(	const number	duration,
		const RampUpType	type
	)

Set a velocity ramp-up for the free jet inflow. If this function is never called or if a ramp-up duration of zero is specified, no ramp-up is applied and the returned velocity values correspond directly to the fully developed velocity field.

Parameters

duration	The duration of the ramp-up.
type	The type of ramp-up function.

value()

template<int dim, typename number >

number MeltPoolDG::CompressibleFlow::FreeJetInflow< dim, number >::value ( const dealii::Point< dim, number > &  location, const unsigned int  component  ) const

final

Evaluates the conservative variable values for the free jet inflow at a given location. The first component specifies whether the locations is inside (return value of 1.0) or outside (return value of 0.0)the jet.

Parameters

loc	The spatial location at which to evaluate the conservative variables.
component	The index of the component to return. For an interpretation of the component indices, see CombinedInflowNoSlipWallValueInterpretation.
