Appropriate boundary treatment technique is one of the greatest challenges found in the Smoothed Particle Hydrodynamics (SPH) Lagrangian method. This paper focuses on the treatment of different boundary condition techniques and their implementation in the SPH code developed by the authors. The boundary conditions implemented and tested in this work involve the use of virtual particles, repulsive force, geometric reflection, and dynamic particle treatments. A code was written in Fortran language in order to solve the system of algebraic equations that result from the application of the SPH method in the discretization of the conservation equations. The implemented boundary conditions are tested and the numerical results are compared with results from non-commercial codes and analytical ones. In general, the numerical results obtained in the present work are in agreement with those reported in the literature.Keywords: Boundary conditions, SPH, Heat transfer, Thermal sciences, Fluid mechanics.

Neste método, o domínio do problema é discretizado empregando partículas que possuem propriedades físicas calculadas a partir das propriedades das partículas vizinhas, por meio de uma interpolação, utilizando uma função de suavização. O método foi aplicado para discretizar e adaptar para SPH um modelo de ruptura de barragem sobre um leito úmido conhecido como Dam-Break in Wet-Bed. Tal modelo, considerado ideal, é empregado nos testes de desempenho, precisão e confiabilidade de modelos matemáticos para validação de métodos numéricos aplicados a problemas de vertedouros em barragens hidrelétricas e ondas em praias. In this work, we present the Lagrangian mesh-free method of particles, Smoothed Particle Hydrodynamics (SPH). In this method, the problem domain is discretized using particles having physical properties calculated from neighboring particles by means of interpolation using a smoothing function. The method was applied to discretize and to adapt the SPH for a model of dam rupture on a wet-bed known as Wet-Dam-Break. This model, considered as ideal, is used in tests of performance, accuracy and reliability of mathematical models for validation of numerical methods applied to spillways problems in hydroelectric dams and waves at beaches.
