[petsc-users] Problems about tolerances set in TS

[Yingjie Wu]

Dear PETSc developers
Hi,

I have recently used TS to solve nonlinear equations with time terms. since
the convergence of my model is not very good, i would like to set to
iterative fixed nonlinear steps per time step. If the problem does not meet
the SNES convergence criteria after fixed number of nonlinear steps , then
go to the next time step calculation. I tried -snes_max_it , but didn't
achieve the effect I wanted, and the program stopped after iterating the
fixed number of steps. How should I set up in the program?


Thanks,

Yingjie
