iteration steps in amg preconditioner

0 votes

Dear all,

I have some questions about the amg preconditioner in the DOLFIN solve() function. Do we use the V-cycle scheme? If so, how many iteration steps in the pre-smoothing and post-smoothing processes and how many grid levels are there? Can I change the number of iteration steps as a parameter in the function?

Thank you very much for your help!
