| 摘 要： | When the red-black subdivisions are satisfied, an iterative substructuring method is proposed to solve the algebraic system of equations arising from the discretization of symmetric elliptic problems via nonconforming finite elements which are only continuous at the quasi-uniform mesh nodes. Theoretical analysis is given and the results of numerical experiments are reported.

| Abstract: | When the red-black subdivisions are satisfied , an iterative substructuring method is proposed to solve the algebraic system of equations arising from the discretization of symmetric elliptic problems via noncomforming finite elements which are only continuous at the quasi-uniform mesh nodes. Theoretical analysis is given and the results of numerical experiments are reported. |
