An Object-Oriented Approach for Parallel Finite Element Analysis

摘要

Scientific computing has historically been performed using simple, efficient languages supporting function-oriented design. This can be seen in the legacy codes written in FORTRAN 77 as well as the newer codes written in C and Fortran 90/95. However, these applications suffer the same problems found in other software written in this fashion. Code reuse is inefficient and prone to error, and changing or modifying the algorithms employed is a highly problematic and time-consuming operation. Accordingly, a new approach has been developed employing the object-oriented design methodology for a large class of computational engineering problems that use the finite element method. The framework has been designed to deliver portability, modularity, extensibility, and efficiency through parallelism.
