An AdaptiveMeshMedium instance represents a transfer medium 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.
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 AdaptiveMeshMedium instance:
\[ \{\, \rho\,(\text{M}_\odot\,\text{pc}^{-3}) \;\;|\;\; M\,(\text{M}_\odot) \;\;|\;\; n\,(\text{cm}^{-3}) \;\;|\;\; N\,(1) \,\} \quad [Z\,(1)] \quad [T\,(\mathrm{K})] \quad [ v_x\,(\mathrm{km/s}) \quad v_y\,(\mathrm{km/s}) \quad v_z\,(\mathrm{km/s}) ] \quad [ B_x\,(\mu\mathrm{G}) \quad B_y\,(\mu\mathrm{G}) \quad B_z\,(\mu\mathrm{G}) ] \quad [ \dots\text{mix family params}\dots ] \]
Depending on the value of the massType option, the first column lists the average mass density \(\rho\), the integrated mass \(M\), the average number density \(n\), or the integrated number density \(N\) for the cell. This quantity is multiplied by the value of the massFraction option.
If the importMetallicity option is enabled, the next column specifies a "metallicity" fraction, which is 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 value of the maxTemperature option, the mass and density for the cell are set to zero, regardless of the mass or density specified in the first column. If the importTemperature option is disabled, or the maximum temperature value is set to zero, such a cutoff is not applied.
If both the importMetallicity and importTemperature options are enabled, this leads to the following expression for the density of an imported cell (or a simular formula for the other mass quantity types):
\[ \rho_\mathrm{imported} = \begin{cases} f_\mathrm{mass}\,Z\,\rho & \mathrm{if}\; T<T_\mathrm{max} \;\mathrm{or}\; T_\mathrm{max}=0 \\ 0 & \mathrm{otherwise} \end{cases} \]
If the importVelocity option is enabled, the subsequent three columns specify the \(v_x\), \(v_y\), \(v_z\) velocity components of the cell (considered as the average bulk velocity for the mass in the cell).
If the importMagneticField option is enabled, the subsequent three columns specify the \(B_x\), \(B_y\), \(B_z\) magnetic field vector components for the cell.
Finally, if the importVariableMixParams option is enabled, the remaining columns specify the parameters used by the configured material mix family to select a particular material mix for the cell.
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.

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

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 ImportedMedium.
