In this work, we propose to combine therecent advances made by the candidate and other researchers of the Laboratório de Computação deAlto Desempenho (LCAD) of ICMC-USP with parallel programming tools of Computational FluidDynamics (CFD), so as to develop a new, advanced code to be used in computational clusters with shared anddistributed memory. To accomplish this, the candidate will perform research and implementation work on: i)a new discretization of the rigid boundary conditions with enhanced stability,ii) a new treatment of the pressure boundary condition inprojection methods for free surface flows, iii) a second order methodbased on the Marker-And-Cell (MAC) scheme, iv) computational packages inlinear algebra and parallel programming; v) a programming platform forhigh performance multi-processor clusters.Therefore, by combining the new techniques developed bythe candidate with the experience of the supervisor in high-performance CFD analysis,we propose the development of a computational packagethat will significantly enlarge the simulating capabilities of technological problems at the LCAD.
