Detailed Description

ClearDensityRecipe is a dynamic medium state recipe mainly intended for testing purposes. The recipe sets the density to zero for all medium components in all spatial cells where the radiation field strength \(U\) exceeds a given threshold value \(U_\mathrm{cut}\) configured by the user. The recipe converges when no additional cells have been cleared after an iteration.

The radiation field strength \(U\) in this recipe is defined as

\[ U = \frac{ \int_0^\infty J_\lambda\, {\text{d}}\lambda }{ \int_0^\infty J_\lambda^{\text{MW}}\, {\text{d}}\lambda }, \]

where \(J_\lambda^{\text{MW}}\) is the local interstellar radiation field in the Milky Way according to Mathis et al. (1983).

Constructor & Destructor Documentation

◆ ClearDensityRecipe()

ClearDensityRecipe::ClearDensityRecipe ( )

inlineprotected

Default constructor for concrete Item subclass ClearDensityRecipe : "a recipe that clears material in cells above a given radiation field strength" .

Member Function Documentation

◆ beginUpdate()

void ClearDensityRecipe::beginUpdate ( int numCells )

overridevirtual

This function is called before an update cycle begins. It caches the radiation field wavelength grid.

Implements DynamicStateRecipe.

◆ fieldStrengthThreshold()

ClearDensityRecipe::fieldStrengthThreshold ( ) const

inline

This function returns the value of the discoverable double property fieldStrengthThreshold : "the field strength above which material is cleared from a cell" .

The minimum value for this property is "[0" .

The default value for this property is given by the conditional value expression "1" .

◆ update()

UpdateStatus ClearDensityRecipe::update	(	MaterialState *	state,
		const Array &	Jv
	)

overridevirtual

This function is called repeatedly as part of the update cycle. If the density of the medium component in the cell under study is nonzero, it calculates the strength of the radiation field. If this value exceeds the configured threshold, the density is set to zero. The function returns UpdatedNotConverged if the density has been updated and NotUpdated otherwise.

Implements DynamicStateRecipe.
