[petsc-users] KSP iteration information out put as an txt file

[Oo]

Dear All,


How to put out the KSP iteration info. as an .txt file?


When I used "-ksp_gmres_restart 200 -ksp_max_it 200 -ksp_monitor_true_residual -ksp_monitor_singular_value",


the information of KSP iterations is printed on the terminal.
How can I put them out to an independent file (like txt file, or other form)?


Thanks,


Meng
