Thanks for the suggestions, I'm going to try both the possibilities. Lorenzo Il giorno 12/ott/2009, alle ore 18.01, John Peterson ha scritto: > On Mon, Oct 12, 2009 at 10:57 AM, Roy Stogner > wrote: >> >> On Mon, 12 Oct 2009, Lorenzo Botti wrote: >> >>> I'm solving the incompressible NS equati

[Libmesh-users] Solving for the increment with Newton method

2009-10-12 Thread Lorenzo Botti
Hi all, I'm solving the incompressible NS equations with a fully implicit dg code and I would like to know if there is an easy way to solve for the increment instead of the solution itself. Sometimes with non-linear fluxes building the residual on the rhs is easier than summing it to the product J*
