Detailed Description

template<class Tvec, template< class > class SPHKernel>
class shammodels::gsph::modules::UpdateDerivs< Tvec, SPHKernel >

GSPH derivative update module.

Computes the acceleration (dv/dt) and energy rate (du/dt) for all particles using the GSPH formulation. For each particle pair:

1. Extract left/right states (rho, v, P)
2. Solve 1D Riemann problem along pair axis to get (p*, v*)
3. Compute force contribution using p* instead of artificial viscosity

Template Parameters

Tvec	Vector type (e.g., f64_3)
SPHKernel	Kernel type (e.g., M4, M6, C2, C4, C6 for Wendland)
