class	pfc::SeedGrid

Detailed Description

Regular grid of crystalline seeds initial condition.

This file defines the SeedGrid class, which places spherical crystalline seeds in a regular 3D grid pattern. Useful for:

• Studying grain growth with controlled initial microstructure
• Investigating grain boundary interactions
• Polycrystalline solidification simulations

The grid spacing and seed properties (size, density, amplitude) are configurable.

Usage:

auto ic = std::make_unique<pfc::SeedGrid>();
ic->set_Nx(4);  // 4x4x4 grid
ic->set_Ny(4);
ic->set_Nz(4);
ic->set_radius(5.0);
simulator.add_initial_condition(std::move(ic));
