Abstract :
A domain decomposition procedure is described that reduces the memory required to solve large finite-elements problems. The procedure involves partitioning a large computational domain into several smaller domains and solving the subdomain problems iteratively. Robin boundary conditions are used at the interfaces between domains to ensure correct field behavior across subdomain boundaries. The procedure and memory savings are illustrated with the analysis of a Rotman lens with and without domain decomposition
