The cut view illustrates the parallel distribution of the entire problem among 32 processes. Black lines indicate the interface position. Left: When solid and fluid domain have been distributed independently, subdomains do not span across the interface. Right: After redistribution based on a monolithic graph, some subdomains contain solid or fluid portions only, while a certain number of subdomains contains solid and fluid portions and span across the interface
