Create a GSPH (Godunov SPH) model.

GSPH uses Riemann solvers at particle interfaces instead of artificial viscosity, giving sharper shock resolution.

Parameters

contextShamrockCtx

Shamrock context

vector_typestr

Vector type, e.g., “f64_3” for 3D double precision (default: “f64_3”)

sph_kernelstr

SPH kernel type: “M4” (cubic spline, default), “M6”, “M8” (quintic spline), “C2”, “C4”, “C6” (Wendland kernels)

Returns

GSPHModel

A GSPH model instance

Examples

>>> ctx = shamrock.ShamrockCtx()
>>> model = shamrock.get_Model_GSPH(context=ctx)  # Uses M4 kernel by default
>>> config = model.gen_default_config()
>>> config.set_riemann_hllc()
>>> config.set_eos_adiabatic(1.4)
>>> model.set_solver_config(config)
