[petsc-users] Cannot open graphic monitor

[张国熙]

Hi,

I tried to open the graphic monitor by
    char  common_options[]      = "-st_ksp_type preonly \
                               -st_pc_type lu \
                               -st_pc_factor_mat_solver_package mumps \
                -eps_tol 1e-9 \
                -eps_monitor_lg_all \
                -draw_pause .2";
ierr = PetscOptionsInsertString(common_options);CHKERRQ(ierr);


Then ./program

But nothing comes out. Should I install any other package first to get it?

Thank you.
