I had slightly misread the code (MG setup doesn't call KSPSetFromOptions more than once even when PCSetUP_MG is called again), but here is an example: cd src/ts/examples/tutorials make ex26 ./ex26 -da_refine 1 -ts_max_steps 10 -ts_rtol 1e-3 -ts_atol 1e-3 -ts_type beuler -pc_type asm -pc_asm_blocks 30 -sub_ksp_type richardson -sub_ksp_monitor Cheers, Lawrence
