The recent efforts in development of efficient solution methods for nonconforming finite element systems are inspired by their importance for various applications in scientific computations and engineering. This study is focused on the implementation of rotated bilinear elements. A locally modified approximation of the global stiffness matrix is proposed(More)
New theoretical and experimental results concerning a recently introduced parallel preconditioner for the solution of large nonconforming FE linear systems are presented. The studied algorithm is based on the modified incomplete Cholesky factorization MIC(0) applied to a locally constructed approximation of the original stiffness matrix. The overlapping of(More)
