Detailed Description

Random distribution of crystalline seeds initial condition.

This file defines the RandomSeeds class, which places spherical crystalline seeds at random locations throughout the domain. Useful for:

• Realistic polycrystalline microstructures
• Statistical studies of grain growth
• Homogeneous nucleation simulations

The number and properties of seeds are configurable. Seeds are randomly positioned using the Mersenne Twister random number generator.

Usage:

auto ic = std::make_unique<pfc::RandomSeeds>();
ic->set_amplitude(0.2);
ic->set_density(0.5);
simulator.add_initial_condition(std::move(ic));
