An Unconventional Domain Decomposition Method for an Efficient Parallel Solution of Large-Scale Finite Element Systems
Copyright policy )An Unconventional Domain Decomposition Method for an Efficient Parallel Solution of Large-Scale Finite Element Systems
A domain decomposition algorithm is developed for the parallel finite element solution of elliptic partial differential equations. Lagrange multipliers are introduced to enforce compatibility at the interface. A conjugate projected gradient algorithm is developed for the solution of the coupled systems. It is suitable for parallel/vector computers with shared memory. The degree of parallelism is not limited by the bandwidth of the finite element system.
