Sentence examples for coarse problem from inspiring English sources

As we know, the technical aspect in DDMs is that the preconditioner includes a coarse problem which can enhance the convergence.

Thus we need not modify the bilinear forms on subdomains, and we can solve each subproblem and coarse problem in parallel.

For some of these methods (e.g. BDDC and FETI-DP), its definition relies on a 'minimal' set of coarse nodes (sometimes called corners) which assures invertibility of local subdomain problems and also of the global coarse problem.

Finally, we introduce coarse spaces based on partitions of unity and planes waves, and show how oblique projection coarse problems can be designed from restricted additive Schwarz methods.

These new methods also extend previous work on non-overlapping balancing domain decomposition methods toward simplifying their coarse problems and local solvers.

Fine behavioural characterization of patients will improve lesion-mapping only if the coarse problems of analysing the underlying anatomy are adequately solved first.

Numerical diffusion is a common problem with many numerical methods when applied on coarse grids.

There are the same difficulties as the parallelizing of the coarse grid problem in the multigrid methods.
