Detailed Description

An AdaptiveMeshSource instance represents a primary radiation source with a spatial and spectral luminosity distribution described by an Adaptive Mesh Refinement (AMR) grid partitioning a cuboidal domain. The data is usually extracted from a cosmological simulation snapshot, and it must be provided in a column text file formatted as described below.

Refer to the description of the AdaptiveMeshSnapshot class for information on the structure of an adaptive mesh and on how to represent it in text column file format. Refer to the description of the TextInFile class for information on overall formatting and on how to include header lines specifying the units for each column in the input file. In case the input file has no unit specifications, the default units mentioned below are used instead. The number of columns expected in the input file depends on the options configured by the user for this AdaptiveMeshSource instance, including the selected SEDFamily.

$[v_{x} (k m / s) v_{y} (k m / s) v_{z} (k m / s) [σ_{v} (k m / s)]] [M_{c u r r} (M_{⊙})] b (1) \dots SED family parameters \dots$

If the importVelocity option is enabled, the first three columns specify the $v_{x}$ , $v_{y}$ , $v_{z}$ bulk velocity components of the source population represented by the cell. If additionally the importVelocityDispersion option is enabled, the next column specifies the velocity dispersion $σ_{v}$ , adjusting the velocity for each photon packet launch with a random offset sampled from a spherically symmetric Gaussian distribution. If the importCurrentMass option is enabled, the next column provides the current mass of the particle, $M_{c u r r}$ . This mass is currently only used for probing the input model. If the importBias option is enabled, the next column specifies the bias parameter, $b$ , which is used to bias the photon sampling for each cell (see the documentation of the ImportedSource class).

The remaining columns specify the parameters required by the configured SED family to select and scale the appropriate SED. For example for the Bruzual-Charlot SED family, the remaining columns provide the initial mass, the metallicity, and the age of the stellar population represented by the cell corresponding to the site. Refer to the documentation of the configured type of SEDFamily for information about the expected parameters and their default units.

Constructor & Destructor Documentation

◆ AdaptiveMeshSource()

AdaptiveMeshSource::AdaptiveMeshSource ( )

inlineprotected

Default constructor for concrete Item subclass AdaptiveMeshSource : "a primary source imported from data represented on an adaptive mesh (AMR grid)" .

Member Function Documentation

◆ createAndOpenSnapshot()

Snapshot * AdaptiveMeshSource::createAndOpenSnapshot ( )

overrideprotectedvirtual

This function constructs a new AdaptiveMeshSnapshot object, calls its open() function, passes it the domain extent configured by the user (using properties offered by the MeshSource base class), and returns a pointer to the object. Ownership of the Snapshot object is transferred to the caller.

Implements ImportedSource.
