[petsc-users] problem with -ts_type gl

Wed Nov 9 07:51:35 CST 2011

Dear all,

I run implicitly my code for the boundary layer over a flat plate, with:

mpiexec -n 1 valgrind ./hoac blasius -snes_mf_operator -llf_flux -n_out 
10 -end_time 50 -implicit -pc_type bjacobi -sub_pc_type ilu 
-sub_pc_factor_mat_ordering_type rcm -gl -ksp_type fgmres 
-sub_pc_factor_levels 2 -snes_monitor -snes_converged_reason 
-ksp_converged_reason -ts_view -ksp_pc_side right -sub_pc_factor_levels 
4 -ksp_gmres_restart 500 -dt 1.0e-3 -snes_ksp_ew -ts_type gl

and I got:

Approximation order = 0
# DOF = 9600
# nodes in mesh = 1281
# elements in mesh = 1200
Navier-Stokes solution
Using LLF flux
