Set adiabatic equation of state: P = (gamma-1) rho u

Parameters#

gammafloat

Adiabatic index (e.g., 5/3 for monatomic gas, 7/5 for diatomic)

set_eos_isothermal(self: shamrock.pyshamrock.model_gsph.GSPHModel_f64_3_C2_SolverConfig, cs: float) → None#

set_reconstruct_piecewise_constant(self: shamrock.pyshamrock.model_gsph.GSPHModel_f64_3_C2_SolverConfig) → None#

Set first-order piecewise constant reconstruction.

Sets all gradients to zero. Most diffusive but most stable. Good for very strong shocks or initial testing.

set_riemann_hllc(self: shamrock.pyshamrock.model_gsph.GSPHModel_f64_3_C2_SolverConfig) → None#

Set HLLC approximate Riemann solver.

Fast approximate Riemann solver that captures contact discontinuities. Recommended for general use - good balance of accuracy and speed.

set_riemann_iterative(self: shamrock.pyshamrock.model_gsph.GSPHModel_f64_3_C2_SolverConfig, *, tolerance: float = 1e-06, max_iter: int = 20) → None#

Set iterative Riemann solver (van Leer 1997).

This is the most accurate but slower Riemann solver. Uses Newton-Raphson iteration to find the pressure in the star region.

Parameters#

tolerancefloat

Convergence tolerance for Newton-Raphson iteration (default: 1e-6)

max_iterint

Maximum number of iterations (default: 20)
