Enumeration Type Documentation

BasePartitionType

enum gridfire::partition::BasePartitionType

Enumerates available partition function implementations.

RauscherThielemann: Uses tabulated normalized G-values and linear interpolation. GroundState: Uses ground state spin (J) to compute partition function as 2J+1.

Enumerator
RauscherThielemann	Rauscher-Thielemann partition function.
GroundState	Ground state partition function.

basePartitionTypeToString

std::unordered_map<BasePartitionType, std::string> gridfire::partition::basePartitionTypeToString

inline

Initial value:

= {
        {RauscherThielemann, "RauscherThielemann"},
        {GroundState, "GroundState"}
    }

Mapping from BasePartitionType enum to human-readable string.

Used for logging, reporting, or serialization. Ensure that all enum values are represented in this map.

Precondition

Contains entries for all values of BasePartitionType.

Postcondition

Can convert BasePartitionType to corresponding string.

RT_TEMPERATURE_GRID_T9

std::array<double, 24> gridfire::partition::RT_TEMPERATURE_GRID_T9

staticconstexpr

Initial value:

= {
        0.01, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5,
        2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0
    }

stringToBasePartitionType

std::unordered_map<std::string, BasePartitionType> gridfire::partition::stringToBasePartitionType

inline

Initial value:

= {
        {"RauscherThielemann", RauscherThielemann},
        {"GroundState", GroundState}
    }

Mapping from string to BasePartitionType enum.

Used for parsing configuration or user input. Strings must match exactly to one of the defined partition types.

Precondition

Uses keys that exactly match the outputs of basePartitionTypeToString.

Postcondition

Can convert valid string identifiers back to BasePartitionType.

Exceptions

std::out_of_range

if accessed with a non-existing key via at().
