 Domain decomposition methods

Domain decomposition methods are numerical techniques used to solve partial differential equations (PDEs) and other mathematical problems by breaking a large computational domain into smaller subdomains. This approach allows for easier problem-solving and can significantly reduce computational time and resource usage, particularly for large-scale problems. ### Key Features of Domain Decomposition Methods: 1. **Subdomain Division**: The main computational domain is divided into smaller, non-overlapping or overlapping subdomains.
