Description:Subdomains for which to add tallies in OpenMC. If not provided, cell tallies will be applied over the entire mesh.
- check_equal_mapped_tally_volumesFalseWhether to check if the tallied cells map to regions in the mesh of equal volume. This can be helpful to ensure that the volume normalization of OpenMC's tallies doesn't introduce any unintentional distortion just because the mapped volumes are different.

CellTally
commentnote
CellTally can only be added to problems when the input files contains a OpenMCCellAverageProblem in the [Problem] block. Otherwise, attempting to add this tally will result in an error.
Description
The CellTally class wraps an OpenMC tally with a distributed cell filter to enable data transfer from CSG cells to a MooseMesh mirror of the OpenMC geometry. The cell to element mapping established by the OpenMCCellAverageProblem is used to facilitate this data transfer to the mesh mirror. When using a CellTally, tally_blocks specifies which blocks in the [Mesh] should be tallied. Then, any OpenMC cells that map to those blocks are added to a cell tally, with one bin for each unique cell ID/instance combination. check_equal_mapped_tally_volumes is used to confirm whether each cell in the CellTally has the same mapped volume on the MooseMesh (to a tolerance specified in equal_tally_volume_abs_tol).
Cardinal supports several tally scores which can be specified in the score parameter when adding a tally. Options include:
heating: total nuclear heatingheating_local: same as theheatingscore, except that energy from secondary photons is deposited locallykappa_fission: recoverable energy from fission, including prompt sources (fission fragments, prompt neutrons, prompt gammas) and delayed sources (delayed neutrons, delayed gammas, delayed betas). Neutrino energy is neglected. The energy from photons is assumed to deposit locally.fission_q_prompt: the prompt components of thekappa_fissionscore, except that the energy released is a function of the incident energy by linking to optional fission energy release data.fission_q_recoverable: same as thekappa_fissionscore, except that the score depends on the incident energy by linking to optional fission energy release datadamage_energy: damage energy productionflux: particle scalar fluxH3_production: tritium production reaction rate
For more information on the specific meanings of these various scores, please consult the OpenMC tally documentation. The names of the tally auxvariables added by the OpenMCCellAverageProblem can be modified by specifying a name for each score in name.
This tally is capable of controlling OpenMC execution through the use of tally triggers. Tallies currently support active batch termination through a relative error indicator, which can be enabled by setting trigger to rel_err for each score in the tally. Scores which do not need to control active batch termination can have a value of none set. If enabled, an appropriate relative error must be set for each score in trigger_threshold.
Certain aspects of tally results can be output as auxiliary variables to the mesh:
unrelaxed_tally: unrelaxed tally; this will append_rawto the tally name and output to the mesh mirrorunrelaxed_tally_std_dev: unrelaxed tally standard deviation; this will append_std_devto the tally and output to the mesh mirror
Example Input File Syntax
As an example, this CellTally scores kappa_fission (the default tally score) on block 0 and stores the result in a variable named heat_source. This corresponds to tallying the heating for three different fuel pebbles.
