New Nonlinear FETI-DP Methods Based on a Partial Nonlinear Elimination of Variables

摘要

We have presented new nonlinear FETI-DP variants based on a partial nonlinear elimination of interior and interface variables. These methods can remove the influence of the coarse space to the Newton convergence and can be superior if a good coarse space is not available. We have seen that the new methods can reduce the number of FETI-DP coarse solves drastically.
