ADDouble

typedef CppAD::AD<double> gridfire::ADDouble

Alias for CppAD AD type for double precision.

This alias simplifies the use of the CppAD automatic differentiation type.

FormatStringLookup

std::unordered_map<NetworkFormat, std::string> gridfire::FormatStringLookup

inlinestatic

Initial value:

= {
        {APPROX8, "Approx8"},
        {REACLIB, "REACLIB"},
        {UNKNOWN, "Unknown"}
    }

MIN_ABUNDANCE_THRESHOLD

double gridfire::MIN_ABUNDANCE_THRESHOLD = 1e-18

staticconstexpr

Minimum abundance threshold below which species are ignored.

Species with abundances below this threshold are treated as zero in reaction rate calculations. This helps to improve performance by avoiding unnecessary calculations for trace species.

Definition at line 56 of file engine_graph.h.

MIN_DENSITY_THRESHOLD

double gridfire::MIN_DENSITY_THRESHOLD = 1e-18

staticconstexpr

Minimum density threshold below which reactions are ignored.

Reactions are not calculated if the density falls below this threshold. This helps to improve performance by avoiding unnecessary calculations in very low-density regimes.

Definition at line 47 of file engine_graph.h.

MIN_JACOBIAN_THRESHOLD

double gridfire::MIN_JACOBIAN_THRESHOLD = 1e-24

staticconstexpr

Minimum value for Jacobian matrix entries.

Jacobian matrix entries with absolute values below this threshold are treated as zero to maintain sparsity and improve performance.
