Detailed Description

An AdaptiveMeshGeometry instance represents a 3D geometry with a spatial density 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. The total mass in the geometry is normalized to unity after importing the data.

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 input file should contain 1, 2, or 3 columns, depending on the options configured by the user for this AdaptiveMeshGeometry instance:

${ρ (M_{⊙} {pc}^{- 3}) | M (M_{⊙}) | n ({cm}^{- 3}) | N (1)} [Z (1)] [T (K)]$

Depending on the value of the massType option, the first column lists the average mass density $ρ$ , the integrated mass $M$ , the average number density $n$ , or the integrated number density $N$ for the cell corresponding to the site. The precise units for this field are irrelevant because the total mass in the geometry will be normalized to unity after importing the data. However, the import procedure still insists on knowing the units.

If the importMetallicity option is enabled, the next column specifies a "metallicity" fraction, which in this context is simply multiplied with the mass/density column to obtain the actual mass/density of the cell. If the importTemperature option is enabled, the next column specifies a temperature. If this temperature is higher than the maximum configured temperature, the mass and density for the site are set to zero, regardless of the mass or density specified in the fourth column. If the importTemperature option is disabled, or the maximum temperature value is set to zero, such a cutoff is not applied.

When an item of this type is used, the names provided by the conditional value expression "AdaptiveMeshInterface" are inserted into the name sets used for evaluating Boolean expressions.

Constructor & Destructor Documentation

◆ AdaptiveMeshGeometry()

AdaptiveMeshGeometry::AdaptiveMeshGeometry ( )

inlineprotected

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

Member Function Documentation

◆ adaptiveMesh()

AdaptiveMeshSnapshot * AdaptiveMeshGeometry::adaptiveMesh ( ) const

overrideprotectedvirtual

This function implements the AdaptiveMeshInterface interface. It returns a pointer to the adaptive mesh snapshot maintained by this geometry.

Implements AdaptiveMeshInterface.

◆ createAndOpenSnapshot()

Snapshot * AdaptiveMeshGeometry::createAndOpenSnapshot ( )

overrideprotectedvirtual

This function constructs a new AdaptiveMeshSnapshot object, calls its open() function, passes it the domain extent configured by the user, configures it to import a mass or a density column, and finally returns a pointer to the object. Ownership of the Snapshot object is transferred to the caller.

Implements ImportedGeometry.
