[petsc-users] Dirichlet boundary condition for a nonlinear system

Hi all,

I am just trying to solve a nonlinear system resulted from discretizating a
hyperelasticity problem by finite element method. When I solve a linear
PDE, I never put boundary solution either in a solution vector or a matrix,
but instead, I put boundary condition to the right hand size (load). How
can I do a similar thing when solving a nonlinear system using a newton
