Abstract Transmissivity of self-affine fractures was computed numerically as a function the grid size. One-million-node (1024 × 1024 nodes) with fractal dimensions 2.2–2.6 were cut into successively smaller (“generations”), and transmissivities computed. The number in each generation increased by factor 4. Considerable scatter transmissivity observed for sizes. Average decreased size, without a...
