Abstract

Two topics will be covered in this Chapter:

• numerical approximation of the solution of nonlinear phase-field transition system;

• numerical approximation of boundary optimal control, governed by phase-field transition system. For both subjects we consider the phase-field system with non-homogeneous Cauchy-Neumann boundary conditions:....
