Schwarz domain decomposition
Web23 Aug 2024 · The Schwarz algorithm proceeds as follows: Start with approximate solutions u( 1 )0 and u( 2 )0 of the PDE in subdomains H 1 and H 2 respectively. Initialize k to 1. Calculate u( j )k + 1 = S ( f, u(3 − j)k ( xj )) with j = 1,2. Increase k by one and repeat 2 until sufficient precision is achieved.
