Abstract

A nonconformal dual-primal finite element tearing and interconnecting (FETI-DP) method is formulated to extend the two-Lagrange-multiplier-based FETI-DP algorithm to deal with nonconformal interface meshes. Robin-type transmission condition is implemented at the subdomain interfaces to preserve the fast convergence of the iterative solution of the global interface problem in a high-frequency large-scale three-dimensional (3D) electromagnetic analysis. Numerical results for simulating of finite antenna arrays are presented to demonstrate the application and efficiency the proposed nonconformal FETIDP methods.
