I am trying to separate system matrix assembly and residual vector assembly
for solving a linear system of equation during a Newton-Raphson method,which
should use an inhomogenous constraint. I am using AffineConstraints class from
dealii. But based on the documentation and my trials, there is no way to apply
inhomogenous constraints on the residual vector without already having an
assembled stiffness matrix. The distribute_local_to_global() function only
using residual vectors applies homogenous constraints by default.
Does anyone know of a solution to this? Thanks in advance.
Take a look at step-77, which has the same premise as what you want to do.
