We consider a class of finite element approximations for fourth-order parabolic equations that can be written as system second-order by introducing an auxiliary variable. In our approach, we first solve variational problem and then optimization to satisfy the desired physical properties solution such conservation mass, positivity (non-negativity) dissipation energy. Furthermore, show existence ...
