File: mld_s_jac_smoother_mod.f90 ! ! Module: mld_s_jac_smoother_mod ! ! This module defines: ! the mld_s_jac_smoother_type data structure containing the ! smoother for a Jacobi/block Jacobi smoother. ! The smoother stores in ND the block off-diagonal matrix. ! One special case is treated separately, when the solver is DIAG or L1-DIAG ! then the ND is the entire off-diagonal part of the matrix (including the ! main diagonal block), so that it becomes possible to implement ! a pure Jacobi or L1-Jacobi global solver. ! module mld_s_jac_smoother use mld_s_base_smoother_mod type, extends(mld_s_base_smoother_type) :: mld_s_jac_smoother_type !
