In this paper, space adaptivity is introduced to control the error in the numerical solution of hyperbolic systems of conservation laws. The reference numerical scheme is a new version of the discontinuous Galerkin method, which uses an implicit diffusive term in the direction of the streamlines, for stability purposes. The decision whether to refine or to… (More)

This contribution gives an overview of current research in applying object oriented programming to scientific computing at the computational mechanics laboratory (LABMEC) at the school of civil engineering – UNICAMP. The main goal of applying object oriented programming to scientific computing is to implement increasingly complex algorithms in a structured… (More)

Motivation • Hydraulic fracturing is a method extensively used in oil industry • To enhance petroleum recovery, fractures are artificially created inside the porous media by applying hydraulic pressure produced by an injected fluid • Usually, numerical simulations use simple models (2d or pseudo3d) which are not suited for high permeability and/or low… (More)

A set of object oriented tools is presented which, when combined, yield an efficient parallel finite element program. Special emphasis is given to details within the concept of the tools which enhance their efficiency. The experience of the author has shown that the design concepts documented are crucial for the efficiency of the issuing code, and that they… (More)

One important characteristic of mixed finite element methods is their ability to provide accurate and locally conservative fluxes, an advantage over standard H-finite element discretizations. However, the development of p or hp adaptive strategies for mixed formulations presents a challenge in terms of code complexity for the construction of… (More)

OOPar is a C++ library which implements an interface to MPI (or other communication library) to offer the user a high level interface for implementing parallel algorithms. Large scale software projects have been parallelized using OOPar and their results will be presented during this presentation. OOPar introduces two concepts to help the programmer in… (More)
