#include "ksp.h" int KSPSetFromOptions(KSP ksp)Collective on KSP
-ksp_max_it | - maximum number of linear iterations | |
-ksp_rtol rtol | - relative tolerance used in default determination of convergence, i.e. if residual norm decreases by this factor than convergence is declared | |
-ksp_atol atol | - absolute tolerance used in default convergence test, i.e. if residual norm is less than this then convergence is declared | |
-ksp_divtol tol | - if residual norm increases by this factor than divergence is declared | |
-ksp_avoid_norms | - skip norms used in convergence tests (useful only when not using convergence test (say you always want to run with 5 iterations) to save on communication overhead | |
-ksp_cancelmonitors | - cancel all previous convergene monitor routines set | |
-ksp_monitor | - print residual norm at each iteration | |
-ksp_xmonitor | - plot residual norm at each iteration | |
-ksp_vecmonitor | - plot solution at each iteration | |
-ksp_singmonitor | - monitor extremem singular values at each iteration |
