Abstract

En 中文
• GPU-based matrix-free (MF) multigrid (MG) methods of SGFEM for interface problems. • Standard FE MG operations can be applied to SGFEM using a Schur complement scheme. • A hybrid MF scheme for FE, enrichment, and intersection parts of SGFEM matrix. • Overall computational complexity is of the same as that of conventional FEM.
