[Libmesh-users] arc-length method

[yunfei z. <yzh...@go...>]

Hi
I am trying to use arc-length method to track the post-buckling equilibrium
path. I need to add another parameter and another additional equation to the
system.
Has anyone got experience on using arc-length together with libmesh and
petsc.
 Is there any Class in libmesh that I can use directly? Thanks.
Best wishes,
yunfei
