[petsc-users] Can I set up the initial guess for the solution vector for the KSP?

[Nan.Jia at Dartmouth.edu]

Dear all,
I am trying to solve a time stepping problem, And I'd like to use the  
solution from the last time step as the initial guess for the  
iterative solver in KSP,for example, the GMRES method. Can I do it by  
calling some routines in PETSc? Thanks in advance.

Best,
Nan
