Field Documentation

n_stored_directions

n_stored_directions

Number of iterations to perform before restarting the solver. This quantity is useful when a GCR or FMGRES is used.

xtra_sles_param

xtra_sles_param

Set of parameters only used in some situations such as the need to solve approximately the A.x = 1 linear system (A is the (1,1)-block matrix). This is a complementary step in the approximation of the Schur complement.

By default, this is a copy of the block11_sles_param with less restrictive convergence criteria
