Detailed Description

template<IsArithmeticOrAD T>
struct gridfire::engine::StepDerivatives< T >

Structure holding derivatives and energy generation for a network step.

Template Parameters

T	Numeric type (double or CppAD::AD<double>).

This struct is used to return both the time derivatives of all species abundances and the specific nuclear energy generation rate for a single network evaluation.

Example usage:

StepDerivatives<double> result = engine.calculateRHSAndEnergy(Y, T9, rho);
for (double dydt_i : result.dydt) {
    // Use derivative
}
double energyRate = result.nuclearEnergyGenerationRate;
