1. Indicadores de erros a posteriori na aproximação de funcionais de soluções de problemas elípticos no contexto do método Galerkin descontínuo hp-adaptivo / A posteriori error indicators in the approximation of functionals of elliptic problems solutions in the context of hp-adaptive discontinuous Galerkin method
In this work we study goal-oriented a posteriori error indicators for approximations by the discontinuous Galerkin method for the biharmonic and Poisson equations. The methodology used for the indicators is based on the dual problem associated with the functional, which is known to generate the most effective indicators. The two main error indicators based o

2. "Simulations of 3D two-phase flows using adaptive methods and phase field models" / "Simulações de escoamentos tridimensionais bifásicos empregando métodos adaptativos e modelos de campo fase"
This is the first work that introduces 3D fully adaptive simulations for a phase field model of an incompressible fluid with matched densities and variable viscosity, known as Model H. Solving numerically the equations of this model in meshes locally refined with AMR technique, we simulate computationally tridimensional two-phase flows. Phase field models of
