Detailed Description

Comprehensive examples of built-in Initial Condition classes.

This example demonstrates:

1. Constant IC - uniform field initialization
2. SingleSeed IC - single crystalline seed
3. SeedGrid IC - regular grid of seeds
4. RandomSeeds IC - random seed distribution
5. FileReader IC - restart from checkpoint
6. Composition patterns - combining multiple ICs
